Miraidon ex Magnezone Deck Guide: Pokemon TCG Pocket

TL;DR: The current representative list is 20 cards: two Magneton, two Magnemite, two Magnezone, two Oricorio, and one Miraidon ex, plus eleven Trainers. A1-098A1-098 Magneton uses Volt Charge to take Lightning Energy from the Energy Zone, B1a-026B1a-026 Magnezone attacks for 90 and can force a coin flip on the next attack, and B3a-019B3a-019 Miraidon ex gathers every Energy in play for a Hadron Ray finish. A3-066A3-066 Oricorio is the ex-protection Basic.

Is the Miraidon ex Magnezone deck good right now? (Quick Answer)

Yes. The public deck tracker updated September 24, 2026 lists Magnezone Miraidon ex at 2.7% meta share, a 51.5% win rate, 145 deck samples, 882 games, 28 tournaments, and a best finish of #1. It labels the archetype S Tier with an evidence score of 94. Those are strong signals for a current guide, with the date window kept visible because Pocket data changes quickly.

The Pokemon TCG Pocket meta tier list puts this deck in the wider format context. Miraidon ex Magnezone is not the most played list in the tracker, yet it has a clear plan and a positive sample. It is a good choice for a player who owns the Crimson Blaze evolution line and wants a deck that wins through Energy management rather than a coin-flip attack.

Key Takeaways for the Miraidon ex Magnezone deck

• The core is two A1-098 Magneton, two B1a-024 Magnemite, two B1a-026 Magnezone, two A3-066 Oricorio, and one B3a-019 Miraidon ex.
• Magneton's Volt Charge attaches a Lightning Energy from the Energy Zone once per turn, which accelerates the deck without consuming the regular turn attachment.
• Magnezone has 150 HP and Mirror Shot for 90. If the opponent tries to attack next turn, a tails flip can stop that attack.
• Miraidon ex has 140 HP. Legendary Drive can switch it in from the Bench and move all Energy in play to it, while Hadron Ray gains 20 damage for each Lightning Energy attached.
• Oricorio has 70 HP and Safeguard, which prevents attack damage from opposing Pokémon ex.
• The public baseline has nine Pokémon and eleven Trainers. The exact Trainer counts are a starting point from 145 tracked lists, not a permanent rule.
• The deck's first job is to protect the Magneton line. The big Miraidon turn comes after the Energy engine has already done its work.

Miraidon ex Magnezone deck core: acceleration, control, and the finisher

The Pokémon package is compact because each slot has a separate job. Magnemite is the Basic that starts the evolution chain. Magneton is the accelerator and sometimes the first attacker. Magnezone is the reliable mid-game body. Oricorio protects against the format's Pokémon ex attackers. Miraidon ex is the closer that turns a board full of small Energy attachments into a single decisive attack.

A1-098A1-098 Magneton is the engine. Volt Charge lets you take a Lightning Energy from the Energy Zone and attach it to Magneton once during your turn. That Energy attachment happens in addition to the Energy you normally receive, which is why the deck can build a large pool while the opponent is still developing. Magneton also has a 60-damage attack, so it can take an early turn when the board does not yet support a Magnezone evolution.

B1a-024B1a-024 Magnemite has 50 HP and Electro Ball for 30 damage. It is a vulnerable opener, so avoid treating it as disposable when the hand does not already contain another Basic or a search effect. The public list plays two copies because the evolution chain is the deck's most important opening sequence.

B1a-026B1a-026 Magnezone is the mid-game anchor. It has 150 HP and Mirror Shot for 90. After that attack, an opponent who tries to attack on the next turn flips a coin, and tails stops the attack. That effect is not a guaranteed lock, but it changes how the opponent values a switch and gives the deck time to finish setting up the Energy pool.

A3-066A3-066 Oricorio gives the list a different kind of defense. Safeguard prevents all damage done by attacks from opposing Pokémon ex, which lets a 70-HP Basic sit Active against a specific class of attacker. Oricorio is not a universal wall. Non-ex attacks and other effects still matter, so use it when it buys a real setup turn rather than placing it in front of every threat.

B3a-019B3a-019 Miraidon ex is the finisher. Its Legendary Drive ability works when you put it from your hand onto the Bench. You may switch it with your Active Pokémon, then move all Energy in play to it. Hadron Ray starts at 20 damage and adds 20 for every Lightning Energy attached to Miraidon. The card rewards patience because the attack scales with the Energy you prepared before the switch.

Miraidon ex is the finisher that gathers the Energy prepared by the Magneton line.

The current 20-card list and what each Trainer slot does

The public tracker page builds its representative list from 145 deck samples in the August 28 to September 19 data window. The Pokémon section is nine cards: two copies each of Magneton, Magnemite, Magnezone, and Oricorio, plus one Miraidon ex. The Trainer section has eleven cards, with search, draw, disruption, recovery, switching, and one flexible item slot.

That structure is more useful than memorizing one unchanging list. The evolution line wants search and draw early, while the Trainer package also has to solve two separate problems: keeping a damaged Active Pokémon from giving away a point, and finding the right turn to switch into Miraidon. A list that cuts every defensive effect for more draw can assemble the engine faster and still lose because the first attacker cannot leave the Active Spot.

The tracker shows two copies of the search Item and two copies of the main draw Supporter in the baseline. The remaining one-of Trainer slots cover Energy search, hand disruption, switching, recovery, and a flexible healing or item effect. The page also lists several one-of attackers, switching cards, Tools, and disruption cards as alternatives seen in smaller numbers. Those are adaptation options, not required additions.

The best first change depends on what is beating you. Add a switching effect when a damaged Magnezone is trapping the Energy engine Active. Add a second way to find Basics when Magnemite is too hard to open. Choose Oricorio at two copies when Pokémon ex attackers dominate the ladder, then reduce it only when non-ex damage makes Safeguard irrelevant.

Magnezone supplies the 150-HP body and Mirror Shot control turn before Miraidon takes over.

Step-by-Step: How to pilot the Miraidon ex Magnezone deck

1. Set the Energy Zone to Lightning. The deck's acceleration and every important attack use Lightning Energy. The 20-card list contains no Energy cards, so the Energy Zone determines whether Magneton, Magnezone, and Miraidon can do their jobs.

2. Mulligan for a Basic and the Magneton line. Magnemite is the ideal first Basic when the hand can reach Magneton, but Oricorio or Miraidon can begin a game when necessary. Keep a search or draw card with the evolution pieces. Return a hand full of Trainers that cannot place a Pokémon on the board.

3. Use Magneton before chasing the knockout. Volt Charge is the reason the deck can keep pace with faster attackers. Attach the extra Energy to Magneton while it is safe, then evolve into Magnezone when the new body will survive or create a useful Mirror Shot turn. Do not move Energy early simply because Miraidon is in hand.

4. Decide whether Magnezone or Miraidon is the first attacker. Magnezone is the safer mid-game attacker when the opponent must respect Mirror Shot. Miraidon is better when several Energy are already in play and Hadron Ray reaches the knockout number. Make that decision before using a search card so the next draw supports the correct line.

5. Use Oricorio against the right target. Put Oricorio Active when the opposing attacker is a Pokémon ex and Safeguard buys a full turn. Switch away when the opponent's damage comes from a non-ex attacker or an effect that does not count as attack damage. A wall that the opponent can ignore is a lost tempo turn.

6. Build the Energy pool across the board. Magneton can hold Energy while Magnezone attacks, and that is often safer than attaching everything to the Active attacker. The deck wants enough Energy in play for Miraidon's Legendary Drive to create a real attack, but it also wants a second attacker ready if Miraidon is forced out.

7. Play Miraidon from hand when the switch matters. Legendary Drive can move all Energy in play to Miraidon, so the timing changes the entire board. Bring it in after the opponent has committed to the current Active Pokémon or when the consolidated Energy reaches the knockout threshold. Avoid exposing a one-Energy Miraidon merely because the ability is available.

8. Keep the last Trainer for the second knockout. The first Hadron Ray often takes the obvious prize. The game is decided by what happens after Miraidon is damaged or the opponent switches. Save one search, switch, or recovery effect so the deck can replace the attacker instead of watching the Energy investment disappear.

Tips for playing the Miraidon ex Magnezone deck into common matchups

Against Pokémon ex heavy decks, Oricorio is a timing card. It can sit Active while the opponent spends a turn finding a non-ex answer or a switching effect. Do not leave it in front of an attacker that Safeguard does not stop. The deck wins that exchange by buying one setup turn, then moving into Magnezone or Miraidon before the opponent has rebuilt.

Against fast non-ex attackers, prioritize Magnezone and the Trainer package. Safeguard is weaker there, so Oricorio should become a bench Basic rather than the center of the defense. Mirror Shot's coin flip can still buy time, but you should expect to win through damage and switching rather than a clean wall.

Against other Lightning decks, the match is usually decided by who protects the evolution chain and who gets the first large Energy consolidation. Keep Magnemite off the Active Spot when possible, use Magneton while it is safe, and avoid moving all Energy to Miraidon until the attack will change the prize race. A premature switch can leave you with a powerful Pokémon and no follow-up.

Against decks that punish a damaged Active Pokémon, play the defensive Trainer slots early enough that you can retreat or heal without breaking the Energy plan. The representative list includes a recovery or healing role for a reason. Miraidon can take the lead, but Magnezone often needs to remain available as the second attacker when the finisher cannot stay Active.

Common mistakes with the Miraidon ex Magnezone deck

Attaching every Energy to the first attacker. The deck has a better destination for stored Energy than the Pokémon that happens to be Active. Keep the Magneton line alive and spread the pool until Miraidon's switch creates a real knockout.

Evolving without checking the next turn. Magnezone is strong, but it is a Stage 2. If evolving consumes the turn you needed to find a Basic, a switch, or a defensive card, the extra HP will not save the position. Plan the Trainer sequence before committing to the evolution.

Using Oricorio as a universal wall. Safeguard only prevents damage from attacks by Pokémon ex. Non-ex attackers, status, switching effects, and other forms of interaction still matter. Treat Oricorio as a matchup tool with a specific target.

Moving Energy to Miraidon too early. Legendary Drive looks powerful whenever Miraidon is in hand. The ability is best when the full Energy pool creates a knockout or changes the Active position at the right moment. A small Hadron Ray leaves the deck without its most flexible resource.

Ignoring the Trainer roles in the representative list. The Pokémon line is easy to see, but the eleven Trainer cards make the deck consistent. Search finds the evolution chain, draw fills the hand, switching repairs a trapped Active, and disruption or recovery decides the turn after the first attack.

Frequently Asked Questions

Is Magnezone Miraidon ex a top deck in Pocket?

It is a current competitive deck with a positive sample. The September 24 public tracker lists 145 samples, 882 games, a 51.5% win rate, 2.7% meta share, and a best finish of #1. That does not make it the universal best deck, but it is enough evidence to build and test the Lightning engine.

How many copies of the core Pokémon should I play?

The representative tracker list uses two Magneton, two Magnemite, two Magnezone, two Oricorio, and one Miraidon ex. Those counts appeared across the tracked baseline, so they are a sensible starting point. The one Miraidon copy reflects its role as a finisher, while the evolution line needs duplicate Basics to open reliably.

Why does Magneton accelerate Energy?

Magneton's Volt Charge attaches a Lightning Energy from the Energy Zone once during your turn. It does not replace the normal Energy attachment, which is why the deck can build a pool while still developing the board. Keep Magneton safe until the stored Energy has a clear destination.

When should Miraidon ex attack?

Miraidon should attack after Legendary Drive gathers enough Energy to reach the needed knockout or to change the prize race. Playing it from hand to the Bench can switch it with the Active Pokémon and move all Energy in play to it. Use that line when the consolidation creates a real board advantage.

Does Oricorio stop every ex deck?

No. Safeguard prevents attack damage from opposing Pokémon ex, which is excellent against a specific attacker but does not stop non-ex attacks, status, switching, or non-attack effects. Put Oricorio Active when the opponent's damage source is one Safeguard actually answers, then return to the main Energy plan.

Is the current tracker list final?

No. It is a representative 20-card list built from 145 tracked deck samples in a dated window. The core Pokémon counts are stable in the page's baseline, while the eleven Trainer slots include several one-of roles that can change with the metagame. Check the live tracker again before an event or a major crafting decision.
