Dragonair Mega Rayquaza ex Deck Guide: 2026 Build List

TL;DR: The pokemontcgpocket.app fan tracker's October 11 snapshot rates the deck S Tier at rank 4, with a 5.4% meta share, a 51.2% win rate, 221 deck samples, 1,266 games, 30 tournaments, and a best finish of first. Dragonair's Dragon's Blessing attaches Energy from the discard pile to an Active Dragon, while Mega Rayquaza ex's Mega Burst deals 50 damage for each Fire and Lightning Energy discarded.

Updated October 12, 2026: Every fact re-checked. Tracker numbers moved to the October 11 snapshot (S Tier, rank 4, 5.4% share), the tracker is now identified as a fan site rather than an official page, the mulligan advice is replaced because Pocket has no mulligan, and matchup win rates from the tracker were added.

Is the Dragonair Mega Rayquaza ex deck competitive? (quick answer)

Yes. The pokemontcgpocket.app fan tracker, which builds its tables from Limitless tournament data, rates this archetype S Tier at rank 4 in its October 11 snapshot. It shows a 5.4% meta share and a 51.2% win rate across 221 deck samples and 1,266 games from 30 tournaments between September 11 and October 9, with a best finish of first. The share is up 1.8 percentage points compared with the tracker's October 4 snapshot, so the deck is still gaining players.

The central exchange is straightforward to describe and tricky to sequence. Dragonair stays on the Bench and returns an Energy from the discard pile to the Active Dragon Pokémon. Mega Rayquaza ex then converts Fire and Lightning Energy into 50 damage per Energy with Mega Burst, discarding the fuel. Gouging Fire gives the deck an earlier attack and a way to contest games where Mega Rayquaza ex would arrive too late.

The Pokemon TCG Pocket complete guide explains the Energy Zone and point system. This guide focuses on the narrow decisions that make the Dragon list work: which Dratini to evolve, when to put a Dragon into the Active spot, and when a discarded Energy is an investment rather than a cost.

Key takeaways for the Dragonair Mega Rayquaza ex deck

• Dragonair belongs on the Bench. Dragon's Blessing needs it there, and the 80 HP Stage 1 should not be offered as the first knockout without a reason.
• Mega Rayquaza ex is a finisher, not an automatic opener. Mega Burst becomes dangerous only after the list has built enough Energy and a way to recover the discard.
• B3a-054B3a-054 Gouging Fire is the early pressure option. It can attack before Mega Rayquaza ex is ready and use Scorching Interruption to reduce the next incoming attack.
• The two Dratini printings have different attacks. Choose the B2b version when a coin-flip 10 plus 20 matters, and the B4 version when two coin flips offer a higher ceiling from the same low-cost Basic.
• B4-155B4-155 Rainbow Cave can discard the Energy generated in the Energy Zone once per turn. Use it to correct a bad generated type or set up the discard-pile plan, not automatically on turn one.
• B3a-072B3a-072 Professor Sada is an Ancient acceleration option, but its three-different-Energy condition is specific. It is not generic draw and should be held until an Ancient Pokémon can use the attachments.
• B3a-069B3a-069 Ancient Booster Energy Capsule adds 40 HP to an Ancient Pokémon. It belongs on Gouging Fire when the extra life changes a return knockout.
• B3b-064B3b-064 Small Balloon reduces the Retreat Cost of an attached Basic Pokémon by one, which matters for Dratini before the evolution line is online.
• B1-225B1-225 Copycat and P-A-007P-A-007 Professor's Research refill a hand that has spent early cards on Dratini, search, and Energy management.

Dragonair Mega Rayquaza ex deck core: recover first, attack second

B2b-051B2b-051 Dratini from B2b has Tail Strike for 10, with a coin flip that adds 20. B4-116B4-116 Dratini from B4 uses Slam for 20 times two coin flips. Neither Basic is a main attacker, but the distinction can matter when the opponent leaves a small Active Pokémon exposed. More importantly, the representative list uses both printings, so check which one is in the opening hand before assuming the two cards play identically.

The representative list runs two Dragonair and two Dragonair targets across one B2b Dratini and one B4 Dratini. That is a narrow evolution package, which makes Poké Ball and early draw important. A Dratini that stays on the Bench is already doing useful work by threatening Dragonair. Do not move it Active merely because its attack can flip for a few extra damage.

Dragonair's Dragon's Blessing is the engine. Once during your turn, while Dragonair is on the Bench, it can attach an Energy from the discard pile to your Active Dragon Pokémon. The ability does not attach to a Dragonair on the Bench, and it does not fix a poor Active choice after the attack has already been declared. Decide which Dragon is attacking first, then use the ability to recover the Energy that makes that attack possible.

Gouging Fire is the early attacker in the current shell, a 110 HP Basic that appears in 93.7% of tracked lists. Scorching Interruption costs Fire, Lightning, and one Colorless Energy, discards two Energy, deals 100 damage, and reduces damage Gouging Fire takes from attacks by 30 during the opponent's next turn. That is a meaningful trade when the opponent would otherwise take a clean point, but it also places two Energy in the discard pile. Dragonair makes that discard useful only after Dragonair is on the Bench and an Active Dragon can receive the recovered Energy.

Mega Rayquaza ex is the closer. It is a 180 HP Basic Pokémon, but it follows the Mega Evolution ex rule: if it is Knocked Out, the opponent gets 3 points. Mega Burst costs one Fire and one Lightning Energy, then discards every Fire and Lightning Energy attached to it, then deals 50 damage for each Energy discarded. Two Energy produce 100, three produce 150, and four produce 200. The attack is powerful because the discarded cards are not necessarily gone for the game. Dragonair can pull one back each turn, and the rest of the list is built to decide when another Energy attachment is worth a point race.

Energy management: Rainbow Cave, Professor Sada, and the discard pile

Rainbow Cave lets each player discard the Energy generated in their Energy Zone once during their turn. That text gives the deck a way to reject a generated Energy that does not match the next attack, but it also gives the opponent the same option. Use the Stadium when replacing the current Energy improves the next two turns, not because an Energy in the Zone feels inconvenient. The same reroll helps Dual Fusion decks that register two Energy types; our dual type cards guide has the odds with and without it.

The best Rainbow Cave turns usually follow a clear decision. If Mega Rayquaza ex needs a Fire and the Zone has generated a different type, discard the generated card only when the next Energy has a realistic chance to complete the attack. If the hand already has Dragonair and the discard pile holds the correct fuel, a Rainbow Cave discard may be less urgent because Dragon's Blessing can solve the problem later.

Professor Sada attaches three different types of Energy from the discard pile to Ancient Pokémon in any way you like. In this list, the target is normally Gouging Fire. The card is powerful when the discard pile and Energy Zone have supplied the required types, but its condition is not a suggestion. Do not spend Sada for a partial dream line, and do not assume it replaces Dragonair's steady one-Energy recovery.

Ancient Booster Energy Capsule gives an Ancient Pokémon 40 more HP. Gouging Fire is the practical target because the extra HP can make the Scorching Interruption turn survive a return attack. Attach the Capsule before the opponent can take a clean point, not after the Ancient attacker has already become a one-hit target.

Small Balloon reduces the Retreat Cost of a Basic Pokémon by one. It is mainly a Dratini tool in this list. That can save a turn when the wrong Basic is Active, but it is not a substitute for deciding which Pokémon should receive the next Energy. If the deck has Dragonair ready and the opponent is threatening a point, use Balloon to preserve the evolution line rather than forcing a weak attack.

P-A-005P-A-005 Poké Ball finds a random Basic Pokémon, which means it is most valuable before the Bench is full of the wrong pieces. Professor's Research draws two and is the clean reset after the hand has spent cards on the evolution package. These Trainers are less exciting than Mega Burst, but missing Dragonair costs more games than failing to find one extra late-game Energy.

GODEEPER: The Pokemon TCG Pocket meta tier list shows where this Dragon shell sits beside the format's faster ex decks and larger samples.

Verified 20-card shell and the role of each slot

The fan tracker's October 11 snapshot reconstructs the list as follows. Dragonair, Mega Rayquaza ex, Poké Ball, Professor's Research, Copycat, and Rainbow Cave appear in 100% of its 221 tracked lists; Small Balloon (68.3%), Cyrus (66.5%), and the B2b Dratini (44.3%) are the flex slots.

The table has an important implication: the list is not built to attack with several unrelated Dragon Pokémon. It has one Mega Rayquaza ex, two Gouging Fire, and a recovery engine that expects Energy to move through the discard pile. That makes the deck more sensitive to an early knockout than a list with multiple copies of its finisher. Protect the evolution line and use Gouging Fire to buy the turn Rayquaza needs.

Copycat is strongest after the opponent has built a large hand for an evolution or a late-game response. Pokemon Center Lady heals 30 damage and removes Special Conditions, so save it for a turn where the healing changes whether a Dragon survives. Cyrus switches one of the opponent's damaged Benched Pokémon into the Active Spot. The deck has little chip damage of its own, so Cyrus is best after the opponent's own Bench damage or an earlier attack has left a support Pokémon damaged, letting Mega Burst take a point efficiently.

Dragonair and Mega Rayquaza ex: when to attack with each Dragon

Gouging Fire should attack when its 100 damage and damage reduction create a better exchange than waiting. A common mistake is to hold it forever because Mega Rayquaza ex is the headline card. That gives the opponent time to evolve, fill the Bench, and take the first point. If Gouging Fire can take the first point and leave two Energy in the discard for Dragonair, it has done its job even if the opponent removes it next turn.

Mega Rayquaza ex should attack when the discarded Energy produces a meaningful threshold. Three Energy for 150 is a clean answer to many regular attackers. Four Energy for 200 can finish larger ex Pokémon, but only take that line when Dragonair, Professor Sada, or the next Energy Zone turn gives the deck a way to continue. A 200-damage attack that leaves the Bench empty and the discard unusable can win one exchange and lose the game.

Dragonair itself should almost never be Active by choice. Its 40-damage Draconic Whip attack is a fallback, not the reason the card is in the deck. Keep it on the Bench, recover Energy before the attack, and let the Active Dragon spend the recovered resource. If Dragonair is forced Active, retreat only when the exchange preserves the evolution line or prevents a point; do not spend a scarce Energy just to make a low-damage attack.

The deck's second Dratini printing offers a small decision point. B2b Dratini's Tail Strike needs one successful coin flip for 30, while B4 Dratini's Slam asks for two flips for up to 40. Neither changes the main plan, but a weak opponent Active can make the difference relevant. Choose the Dratini that creates the safer evolution path first and take the small attack only when it does not delay Dragonair.

Step-by-Step: How to pilot the Dragonair Mega Rayquaza ex deck

1. Set the Energy plan before the first attachment. Identify whether the opening hand points to Gouging Fire or Mega Rayquaza ex, then protect the Energy types that attack needs. Rainbow Cave is a correction tool, not permission to attach without a plan.

2. Pick the opening Active with the Dragonair line in mind. Pocket has no mulligan: the five-card opening hand always contains a Basic Pokémon. Lead with Gouging Fire when you can, put Dratini on the Bench, and spend Poké Ball or Professor's Research on finding Dragonair. Avoid leading with Mega Rayquaza ex, since losing it early gives up 3 points.

3. Put Dragonair on the Bench before spending the discard. Gouging Fire can discard two Energy for its attack, but that exchange is much better when Dragon's Blessing is ready to return one. If Dragonair is not developing, use the safer attack or preserve the resource.

4. Use Gouging Fire to claim the first useful point. Do not wait for the perfect Mega Rayquaza ex hand if Gouging Fire can take the Active and reduce the return damage. The early point also makes the opponent respect the backup attacker.

5. Cycle Rainbow Cave only for a known threshold. Discard the generated Energy when the next type improves a specific attack, a Professor Sada line, or a Dragonair recovery turn. If the card does not change the next two turns, keep the Energy and use the Stadium later.

6. Recover Energy before declaring the attack. Use Dragon's Blessing while Dragonair is on the Bench, choose the Active Dragon that will actually attack, and only then decide whether the attack should spend the recovered resource. Do not move Dragonair Active before the ability resolves.

7. Decide how much Fire and Lightning to attach before Mega Burst. The attack discards every Fire and Lightning Energy on Mega Rayquaza ex, so the damage is set by what you attached before attacking, not chosen at the moment of the attack. Two Energy for 100 can be correct when it takes a point and keeps a follow-up. Build to three or four only when the higher number changes the knockout and the deck can still recover after the discard.

8. Use Professor Sada as an Ancient turn, not a draw spell. Wait until Gouging Fire can receive the different Energy types and attack or survive because of them. If the condition is not live, Professor's Research is the card that advances the hand.

9. Close by preserving one recovery route. After Mega Rayquaza ex takes a point, keep Dragonair alive, keep one Energy recovery card or Zone turn available, and use Cyrus on a damaged target when it creates the next knockout. Do not empty every resource for a single final attack unless it ends the game.

Matchup plans for the Dragonair Mega Rayquaza ex deck

The tracker's matchup table puts the most common opponent, Mega Altaria ex Espeon, at a 45.4% win rate over 141 games, and the best result at 71.4% over 70 games against Mega Lucario ex Lucario.

Against fast ex decks, Gouging Fire is usually the important card. Make the 100-damage attack before the opponent has a fully developed Bench, and use the 30-damage reduction to force a weaker return turn. If Dragonair is already in play, the discarded Energy is not wasted. If it is not, do not assume the deck can recover from an early two-Energy discard.

Against evolution decks, target the line before it reaches its Stage 2 attacker. Mega Rayquaza ex can take a clean point once it is powered, but giving the opponent two turns to build a Bench makes every later attack more expensive. Use the Mega Sceptile ex Greninja deck guide as a reminder that the opponent may value a safe Stage 1 Bench more than an early Active attack.

Against the Mega Manectric ex Heliolisk list, a 47.7% matchup over 44 games on the tracker, keep the first Dragonair out of the Active spot and watch the Bench spread. Heliolisk's 10 damage to every Benched Pokémon can make Dragonair vulnerable before it evolves. The Mega Manectric ex Heliolisk deck guide explains that spread plan. Evolve the damaged Basic promptly, then use Gouging Fire to punish the Lightning deck for spending its early turn on chip.

Against Suicune ex Baxcalibur, the tracker's biggest risk at 29.1% over 55 games, the race is about which engine gets value first. Suicune ex draws a card at the end of each turn it spends in the Active Spot, while Dragonair turns the discard into Energy. The Suicune ex Baxcalibur deck guide shows why a Water engine becomes dangerous once Baxcalibur is online. Attack with Gouging Fire before that happens, and save Mega Burst for a target that cannot be healed or retreated safely.

Against Mega Blaziken ex Greninja, protect the Dragonair line from the early Fire attack and do not fill the Bench without a reason. Greninja's Bench damage can soften Dratini, while Mega Blaziken ex reaches 120 without waiting for a long Energy chain. The Mega Blaziken ex Greninja deck guide covers that pressure curve. Use Small Balloon or Pokemon Center Lady when either card saves the evolution turn, not as an automatic response to any damage.

Common mistakes with the Dragonair Mega Rayquaza ex deck

Treating Mega Rayquaza ex as the opener. The ex attacker is strongest after the deck has taken a point or built a discard pile. Gouging Fire is there to contest the early game.

Discarding Energy before Dragonair is ready. Gouging Fire and Mega Burst both spend Energy. If Dragonair is not on the Bench, count that cost as permanent unless Professor Sada can return it to Gouging Fire.

Using Rainbow Cave because the generated type looks wrong. The Stadium changes the Energy Zone for both players. Discard only when the next type crosses a known attack or acceleration threshold.

Playing Professor Sada as a weaker Research. Sada has a specific Ancient condition and a powerful payoff. If the discard pile does not contain the needed three different types, save the card or use ordinary draw instead.

Leaving both Dratini on the Bench without evolving. The list has a narrow evolution package. Search for Dragonair before the opponent's spread damage or hand disruption makes the line harder to assemble.

Spending four Energy for a 200-damage Mega Burst without a follow-up. A huge knockout is not automatically the best attack. Keep one recovery path or end the game with the exchange.

What players are saying about the Dragonair deck

ScytheApollo's October 2 video plays the same Gouging Fire into Mega Rayquaza ex plan. In an r/PTCGP thread titled "Mega Ray + Gouging Fire Deck Absolutely Rules," the top reply was short: "Gouging Fire is pretty nuts. It can take on Exs head on." Another player in the same thread described a different build: "I run 2 Sada in mine and ditched the HP booster," using Rainbow Cave to fill the discard pile for Sada and Dragonair.

Our take

Based on the tracker data and card text cited above, this is one of the stronger Pocket decks right now, and Gouging Fire is the reason. Rank 4 with a share still rising week over week says players are finding it, while a 51.2% win rate says it is good rather than dominant. The real weakness is the matchup table: 29.1% into Suicune ex Baxcalibur and 32.8% into Hoopa ex Mega Absol ex. If your ladder is full of those, pick something else; otherwise build the 20-card list as shown and treat Small Balloon and Cyrus as the slots to change.

Frequently Asked Questions

Is the Dragonair Mega Rayquaza ex deck competitive in Pokemon TCG Pocket? Yes. The pokemontcgpocket.app fan tracker's October 11 snapshot rates it S Tier at rank 4, with a 5.4% meta share, a 51.2% win rate, 221 deck samples, 1,266 games, 30 tournaments, and a best finish of first for September 11 through October 9. That is a real archetype, but tracker numbers change daily.

What does Dragonair do in this deck? Dragonair's Dragon's Blessing attaches an Energy from the discard pile to your Active Dragon Pokémon once during your turn while Dragonair is on the Bench. It turns the deck's discarded Energy into future attacks and makes Dragonair a setup piece rather than an attacker you should expose early.

What is the core of the Dragonair Mega Rayquaza ex deck? The tracker's representative list runs two Dragonair, two Gouging Fire, one Mega Rayquaza ex, one Dratini from B2b, one Dratini from B4, two Copycat, two Rainbow Cave, two Poké Ball, two Professor's Research, Professor Sada, Pokémon Center Lady, Ancient Booster Energy Capsule, Small Balloon, and Cyrus. Both Dratini printings evolve into Dragonair.

What Energy does Mega Rayquaza ex need? Mega Burst costs one Fire and one Lightning Energy, then discards all Fire and Lightning Energy attached to Mega Rayquaza ex and deals 50 damage for each one discarded. The tracker lists Fire and Lightning as the deck's Energy types, so manage the Energy Zone and the discard pile together.

What opening hand do you want with Dragonair Mega Rayquaza ex? Pokemon TCG Pocket has no mulligan: the opening hand is five cards and always contains at least one Basic Pokémon. The best starts pair Gouging Fire as the Active with a Dratini on the Bench, plus Poké Ball or Professor's Research to find Dragonair. Mega Rayquaza ex is also a Basic, but avoid making it your first Active.

How does Gouging Fire fit the Mega Rayquaza ex deck? Gouging Fire is the Ancient early attacker and appears in 93.7% of tracked lists. Scorching Interruption costs Fire, Lightning, and one Colorless Energy, deals 100 damage, discards two Energy, and makes it take 30 less damage from attacks during the opponent's next turn. Dragonair and Professor Sada can return the discarded Energy.
