Mega Lucario ex Deck Guide: 3,971 Matches, 49% Win Rate

Updated October 9, 2026: corrected the set for Mega Lucario ex, Korrina and Arena of Antiquity. Limitless lists all three in Pulsing Aura (B3), not Team Rocket's Ambition. Mega Lucario ex is also reprinted in the time-limited Deluxe Pack: Mega.

Update, September 14, 2026: pokemon-zone.com's tracker now shows Mega Lucario ex Lucario at 3,971 matches and a losing 48.9% win rate, down from 52.2% across 1,239 matches at original publish, and it has fallen from A tier to B tier. It's still the format's second-most-played deck by raw volume, but Mega Altaria ex Espeon is now the format's top deck, and Mega Altaria ex specifically is the confirmed hard counter to Lucario described below. The archetype has also grown to 10 tracked variants, 4,492 total matches. One of them, Mega Lucario ex Hitmonchan ex, is a striking cautionary tale: it posted a 66.7% win rate on 30 matches at original publish and has since collapsed to 45.9% over 85 matches, dropping to D tier.

TL;DR: Mega Lucario ex Lucario is now a B-tier deck, 3,971 matches, a losing 48.9% win rate, down from 52.2% at original publish. Its attack, Fighting Pulse, hits for 90 damage in its cheap mode and 140 in its expensive mode, enough to one-shot most Pokemon ex. Support comes from the regular Lucario card plus Korrina and Arena of Antiquity. Its two confirmed weaknesses are a damage cap from the Lucario support card's one-copy-active "Fighting Coach" effect, and a bad matchup against Mega Altaria ex, which is now the format's #1 deck. No verified full decklist exists yet, that part is honestly a gap, not filled in here.

Is Mega Lucario ex the Best Deck in Pokemon TCG Pocket? (Quick Answer)

No, not anymore. Mega Lucario ex Lucario has fallen to B tier, 3,971 matches at a losing 48.9% win rate, down from a winning 52.2% across 1,239 matches when this guide was first published. It's still the format's second-most-played deck by raw volume, second only to Butterfree Mega Sceptile ex, but volume without a winning record no longer earns a top-tier slot. Mega Altaria ex Espeon holds that spot now, which matters directly for this deck, since Altaria is also Lucario's clearest confirmed bad matchup.

Key Takeaways

• Mega Lucario ex Lucario has dropped to B tier: 3,971 matches, a losing 48.9% win rate, down from 52.2% at original publish
• The broader Mega Lucario ex archetype now spans 10 variants and 4,492 total matches at a 48.6% combined win rate since Team Rocket's Ambition launched
• Fighting Pulse deals 90 damage in its base mode and 140 damage for one extra Energy, high enough to one-shot most Pokemon ex
• Support comes from the regular Lucario card, Korrina, and Arena of Antiquity
• The deck's damage ceiling is capped because only one copy of Lucario's Fighting Coach effect can be active at a time
• Mega Altaria ex is a confirmed bad matchup, and it's now the format's top-ranked deck, making this weakness more relevant than ever
• Mega Lucario ex Hitmonchan ex, a promising 66.7%-win-rate variant at original publish, has since collapsed to 45.9% over a larger sample, a clear regression case
• No verified full decklist exists yet for this build

Mega Lucario ex: Archetype Overview and Which Build to Play

"Mega Lucario ex" isn't one decklist, it's an archetype with ten tracked variants in the current metagame, totaling 4,492 matches and a 48.6% combined win rate since Team Rocket's Ambition launched. That combined rate sitting under 50% is itself new information: at original publish, seven variants combined for a winning 52.5%. The archetype as a whole has cooled off, not just its mainline build.

The mainline build, Mega Lucario ex paired with the regular Lucario support card, is the one this guide is actually about, and it's still the proven, most-battle-tested version by a wide margin: 3,971 of the archetype's 4,492 total matches, across 202 different decklists. That's real, continued convergence on a working build, not a handful of hot streaks, but the win rate behind that volume has fallen to a losing 48.9%, down from 52.2% at original publish.

Two more variants are worth naming for how differently they've aged. A solo Mega Lucario ex build, no Lucario support piece at all, sat at a strong 62.3% over 53 matches at original publish. Its sample has since grown to 130 matches and its win rate has settled to 52.3%, still positive, and a textbook example of a small hot sample regressing toward a more sustainable number as more games get logged. A newer pairing, Mega Lucario ex Team Rocket's Raticate ex, has since emerged with the best win rate of the three named variants, 53.4% over 88 matches, though that sample is still small enough to watch rather than trust fully.

Mega Lucario ex Hitmonchan ex tells the more dramatic version of the same story. At original publish it posted a 66.7% win rate over just 30 matches, flagged here as "a genuine but unproven higher-ceiling option." That sample has since grown to 85 matches, and the win rate has collapsed to 45.9%, dropping the variant to D tier. It's the clearest, most concrete regression case in this entire archetype, exactly the outcome a small hot sample risks once the games catch up to it.

I'd still rather build the version with nearly 4,000 games behind it than a 85-match D-tier variant, even though the mainline build's own win rate has fallen below 50%. A large, well-tested losing-but-close deck tells you more about what to expect than a small sample at any win rate. If you want the deck with the largest, most battle-tested track record, that's still the Lucario pairing. If you're looking for a genuinely rising option instead, Team Rocket's Raticate ex is the one worth watching now, not Hitmonchan ex.

Fighting Pulse: The Attack Math That Carries the Deck

The whole deck runs on one attack. Mega Lucario ex has a single move, Fighting Pulse, and it operates at two power levels depending on how much Energy you've committed. The base mode deals 90 damage. Paying one additional Energy bumps that to 140 damage, a number specifically high enough to one-shot most regular Pokemon ex in a single hit.

That's the entire strategic core of the deck, and it's simpler than it sounds. You play a cheaper 90-damage Fighting Pulse turn when you don't have the extra Energy online yet, then a 140-damage Fighting Pulse turn once you do. The second version is strong enough on its own to knock out most opposing ex Pokemon without needing any additional damage boost that turn. There's no combo piece to assemble and no complicated sequencing puzzle. The skill is in timing when to commit the extra Energy and which turn to fire the expensive mode, not in setting up an elaborate engine first. This part of the deck hasn't changed since original publish, and the falling win rate isn't a sign the attack got worse, it's a sign more of the field has learned to play around it.

Damage support layers on top of that base math rather than replacing it. The regular, non-Mega, non-ex Lucario card contributes its own effect, and two Trainer cards released in the same Pulsing Aura expansion, Korrina and Arena of Antiquity, add to the total. None of these pieces change what Fighting Pulse does on its own. They exist to make the 140-damage turns land more consistently and to push past that threshold when a matchup calls for extra damage.

The Deck's Real Weaknesses: Fighting Coach's Cap and Mega Altaria ex

No deck this widely played is weakness-free, and this one has two specific, confirmed problems worth knowing before you build it, one of which has only gotten more relevant since original publish.

The first is a structural cap on the deck's own damage ceiling. Mega Lucario ex evolves from the same base Pokemon line as an older, separate Lucario support card from an earlier set, Space-Time Smackdown, one of the only real Fighting-type support pieces in the whole game. That card's ability, Fighting Coach, is what contributes to Mega Lucario ex's damage output. The catch is that most builds can typically only get one copy of that effect active at a time. Running extra copies of the support Lucario doesn't stack the bonus the way a player might expect, which puts a real ceiling on how much extra damage the deck can generate beyond Fighting Pulse's own numbers.

Note: This guide covers the confirmed attack math, support cards, and known weaknesses for Mega Lucario ex Lucario, not a full card-by-card decklist. No verified 20-card breakdown with exact Trainer or Energy counts has been published for this build yet. Treat that as an honest gap, not an oversight.

The second weakness is a matchup problem, and it matters more today than it did at original publish. Mega Lucario ex is weak to Dragon typing, and the Mega Altaria ex Espeon deck is the single top-ranked deck in the current metagame. That weakness isn't cosmetic. It triggers a 20-damage bonus for Altaria's attacks against Lucario, a meaningful swing in a format where Fighting Pulse's own numbers are already precisely tuned around one-shotting Pokemon ex. Against Altaria, the math that makes Fighting Pulse so efficient elsewhere works against you instead, and you'll be facing that specific matchup more often now that Altaria has climbed to the top of the format.

Neither weakness fully explains the drop from 52.2% to 48.9% on its own, that's a broader field-adaptation effect across thousands of matches, not a single bad matchup. But both are worth planning around rather than discovering mid-match, and the Altaria matchup specifically deserves more attention now than it did a few weeks ago.

Step-by-Step: Piloting the Mega Lucario ex Lucario Game Plan

1. Open with the 90-damage Fighting Pulse whenever the extra Energy isn't online yet. There's no reason to hold the attack back waiting for the expensive mode. The base 90 damage still trades with plenty of early-game threats, and passing up free damage just to wait costs you tempo you don't get back.

2. Commit the extra Energy toward the 140-damage mode as soon as it's realistically reachable. That threshold is the whole point of the deck. Once you can reliably fire the 140-damage version, most opposing Pokemon ex die to a single hit, and that's the swing that wins games.

3. Get the regular Lucario support card into play early, but don't stack extra copies expecting a bigger bonus. Fighting Coach's effect caps at one active copy in most builds. A second Lucario on the bench isn't adding a second stack of damage, so use that bench slot for something else once the first copy is active.

4. Play Korrina and Arena of Antiquity to close the gap on tougher targets. Both Trainer cards exist to push Fighting Pulse's damage further when 140 alone isn't quite enough, which matters most against bulkier ex Pokemon or anything with its own damage reduction.

5. Watch for Mega Altaria ex specifically and adjust your sequencing against it. With Altaria now the format's most common top-tier deck, you'll see this matchup often. The Dragon-type weakness means Altaria's attacks land harder against you than the raw numbers elsewhere in this matchup would suggest. If you know or suspect you're against Altaria, prioritize getting to the 140-damage mode faster rather than trading evenly on 90-damage turns, since you'll be absorbing bonus damage the whole game.

Tips for Playing Mega Lucario ex Lucario

Don't fire the expensive Fighting Pulse mode purely because you can. The 140-damage version is strong specifically because it one-shots most ex Pokemon. If the target on board doesn't need that much damage, a 90-damage hit that still gets the KO saves the extra Energy for a turn where it actually matters.

Track your path to Fighting Coach's single active copy every game. Since the effect doesn't stack, knowing whether it's already online changes how you value drawing a second Lucario. Early in a match that second copy is a backup plan if the first gets knocked out. Later, it's often closer to a dead card.

Respect how differently the named build variants have aged. The Lucario pairing's 3,971-match sample is the deck's real track record, even at a losing 48.9%. Mega Lucario ex Hitmonchan ex looked like a hidden gem at 30 matches and 66.7%; at 85 matches it's a D-tier deck at 45.9%. Don't trust a small sample's win rate over a large one's, in either direction.

Mulligan and sequence differently against known Altaria players. A hand built to grind through Fighting Pulse's normal curve is a worse hand against a matchup where you're already eating extra damage every exchange. Recognize that matchup as early as possible and lean toward speed over efficiency, and expect to see it more often now that Altaria leads the format.

Common Mistakes With Mega Lucario ex

Assuming more Lucario copies means more damage. This is the single most common misplay with the deck. Fighting Coach's effect caps at one active copy in most builds, so drawing or benching a second Lucario expecting a bigger bonus is a misunderstanding of the card, not a bonus waiting to be unlocked.

Assuming a high win rate on a small sample is the better deck. Mega Lucario ex Hitmonchan ex is the cautionary tale here: 66.7% over 30 matches looked like a real signal, and it evaporated to 45.9% once the sample reached 85 matches. Don't chase a hot small sample over the mainline build's much larger, more proven track record.

Underrating the Mega Altaria ex matchup going in. Because Fighting Pulse's math is so efficient against most of the field, it's easy to walk into the Altaria matchup expecting the same math to hold. It doesn't, and with Altaria now the format's #1 deck, you'll face this exact problem more often, not less.

Building from an unverified decklist found online. No confirmed, card-by-card 20-card list for this build has been published as of this writing. Build from the confirmed pieces, the attack math, the three support cards, and the two known weaknesses, rather than copying a list you can't verify against real tournament results.
