340 HP is the reason I stopped laughing at Mega Lucario ex after Pulsing Aura dropped in May 2026. The Mega Lucario ex deck is now a real A-Tier ladder pick, and if you're checking a Pokemon TCG Pocket tool while tuning lists, the short version is simple: build around fast Fighting Energy flow, then hit clean numbers with Mega Brave. Gardevoir ex rotating out matters a ton too, because that old Psychic pressure used to make this whole plan feel cursed.


Is the Mega Lucario ex deck good in the May 2026 meta?
Yes, it's good. Not broken. Good. I've been playing the ASC 113 Riolu into Mega Lucario ex line, and the deck wins because it doesn't ask you to be cute. Aura Jab gets the board moving with 50-plus damage and Energy acceleration, then Mega Brave slams for 250, which deletes most Basic ex and Stage 1 ex Pokémon. Against chunky Stage 2 ex cards sitting around 280 to 330 HP, though, you need help from Premium Power Pro, Gravity Mountain, or Arena of Antiquity.


Best Mega Lucario ex build: Solrock, Lunatone, or aggro-control?
I like the Solrock and Lunatone version for ranked grind, even if it occasionally bricks in the dumbest way possible - not gonna lie, I burned through three games testing greedy hands before cutting back. Lunatone's Lunar Cycle lets you pitch Energy to draw, which feels great when your count is high enough. Solrock's Cosmic Beam also gives you a single-prize poke, and that matters when you don't want to hand over two prizes too early. Hariyama from MEG 73 is the spicy bit: Heave-Ho Catcher drags something like Fezandipiti ex active when it evolves, so your Supporter slot stays open. That's gross in the best way.


Energy counts are where people get a little too clever. Don't. I wouldn't go below 10, and 12 or 13 feels much better if you're running Lunar Cycle hard. You need attachments, discard fuel, and Aura Jab targets all at once, so a low Energy list just trips over itself. Rocky Fighting Energy is also a no-brainer into Alakazam-style decks, since it blocks damage counter placement from Powerful Hand. Your 340 HP means less if the opponent just sidesteps normal damage math.


What ACE SPEC should you run with Mega Lucario ex?
Secret Box is my pick right now, mostly because it fixes the weird turns. Grabbing an Item, Tool, Supporter, and Stadium in one shot can set up Premium Power Pro, Lillie's Determination, and Gravity Mountain without praying to RNG. Maximum Belt is flashier, sure, and the extra 50 damage into ex Pokémon can steal games. I'm not sold on Hero's Cape unless your local queue is all slower decks, while Scoop Up Cyclone has a funny use: reset Hariyama and do the gust trick again. It sounds goofy until it wins a match.


Mega Lucario ex matchups and mistakes to avoid
Bench discipline is the boring lesson, but yeah, it wins games. If you flood the board with Solrock and Lunatone, Suicune ex and Mega Slowbro ex can farm your back line while Lucario sits there looking tough. Lead with single-prize attackers when you can, then bring Mega Lucario ex in once the trade favors you. Darkrai is still scary too, especially the newer Psychic angle, so save Judge or Rocky Energy instead of firing them off because your hand feels awkward. Also, take the Mega Brave damage reports with a grain of salt; some sheets still list 210 instead of 250, and the retreat cost data isn't clean yet.


My current verdict: this is a fighter's deck, not a puzzle box. You win by knowing your knockout math, keeping the bench lean, and using Fighting Gong plus Night Stretcher so early pressure doesn't wreck your plan. If you're grabbing game items, currency, or just comparing player-side services through RSVSR, keep the same mindset here: spend only where it helps the build, because Mega Lucario ex punishes sloppy deck space fast.

Running the Solrock/Lunatone variant of Mega Lucario ex has totally changed how I approach the prize trade - leading with Solrock to bait single-prize attacks before dropping the 340 HP wall feels filthy. I grabbed my missing Hariyama and Secret Box copies through rsvsr at after weeks of bad pulls, and the deck finally clicked.
