Mega Lucario ex Deck Guide: The Post-Rotation Powerhouse That OHKOs Everything
If Dragapult ex is the deck to beat, Mega Lucario ex is the deck built specifically to beat it.
With Gardevoir ex finally gone from Standard, Fighting-type decks are breathing easy for the first time in over a year. Mega Lucario ex, a 340 HP Stage 1 that hits for 270 damage with a single two-energy attack, has quietly become one of the most threatening decks in the post-rotation meta.
This guide breaks down everything: how the deck works, the full 60-card list, and how to approach every major matchup.
Why Mega Lucario ex Is So Good Right Now
Three things happened with the 2026 rotation that made Mega Lucario ex much better overnight.
First, Gardevoir ex rotated out. Gardevoir's Psychic type meant it hit Lucario for double damage. With Gardevoir gone, the single biggest obstacle for Fighting-type decks has been removed from the format.
Second, the field slowed down. The loss of Squawkabilly ex means aggressive turn-one setups are harder for everyone. This slightly longer setup window actually benefits Mega Lucario ex, which wants to get its Stage 1 evolution into play before pressuring the opponent.
Third, everything big is now beatable. With 340 HP and Mega Brave hitting for 270 damage, boosted further by Premium Power Pro and Maximum Belt, Mega Lucario ex can one-shot almost everything legal in the current format, including opposing Mega exes.
How the Deck Works
Mega Lucario ex is a straightforward aggressive deck. The game plan has three steps.
Step one: set up Mega Lucario ex fast. The deck runs four copies of Riolu and three copies of Mega Lucario ex, plus the Solrock/Lunatone draw engine. The goal is to have Mega Lucario ex attacking by turn two.
Step two: attack efficiently. Mega Brave costs just two Fighting Energy and hits for 270 damage. The first attack, Power Up, hits for 130 and attaches an energy from your deck to a Benched Pokémon, effectively accelerating your second Lucario while the first is attacking.
Step three: push through big numbers. Premium Power Pro adds 30 damage for each copy you play that turn. Maximum Belt adds damage and gives your Lucario built-in protection. Stack these tools and you are hitting for numbers that one-shot everything in the format.
Hariyama is a critical support piece. It acts as a gusting tool, a replacement for Boss's Orders, letting you pick specific targets off your opponent's bench without spending your Supporter for the turn.
Solrock and Lunatone work together as your draw engine. Lunatone's Ability draws cards when certain conditions are met, and Solrock searches for your Fighting Energy. Together, they give the deck remarkable consistency without relying on a single Supporter.

Key Cards Explained
Fighting Gong
A new Trainer from Mega Evolution - Perfect Order that boosts Fighting-type attacks. Critical for hitting the damage math needed to one-shot large Mega ex Pokémon.
Stone Fighting Energy
Reduces incoming damage by 20 and prevents residual damage from attacks like Dragapult's Phantom Dive. Turns your already-massive 340 HP Lucario into an even harder wall to break through.
Maximum Belt (ACE SPEC)
Acts as two damage modifiers in one card. When your math is short against specific matchups like Dragapult ex or Arboliva ex, this gets you over the threshold for a one-hit knockout.
Cornerstone Mask Ogerpon ex
A tech pick for walls and troublesome Pokémon. Its ability to ignore all effects on the defending Pokémon punishes decks trying to hide behind protection effects.
Gravity Mountain
A Stadium that makes all Pokémon with a special Energy attached have no Abilities. Useful against decks that rely heavily on Ability-based setup.
Matchup Overview
| Matchup | Rating | Notes |
|---|---|---|
| Dragapult ex | Favorable | Stone Fighting Energy blunts Phantom Dive. Aggressive KOs before Dusknoir sets up. |
| Teal Mask Ogerpon / Meganium | Unfavorable | Grass hits Fighting for weakness; smaller attackers complicate prize trades. |
| Mirror | Even | Draw quality and who lands Mega Brave first; Solrock/Lunatone online first often wins. |
| Alakazam | Slightly Favorable | High HP buys time vs. counter placement; you should close before they fully stabilize. |
Tips for Playing the Deck
- Do not forget Hariyama. It is your best way to gust without using your Supporter.
- Save Premium Power Pro for the turn you need the KO number. Items stack, but opponents can count them.
- Use Power Up early to accelerate energy unless Mega Brave is a guaranteed KO.
- Gravity Mountain against Ability-heavy decks can stall their setup dramatically.
Bottom Line
Mega Lucario ex is the best answer to Dragapult ex in the current format, and it wins on its own merits beyond just being a counter. 340 HP, 270 damage for two energy, and a built-in energy acceleration attack make it a legitimate top-tier deck in its own right.
If Dragapult is the king of post-rotation Standard, Mega Lucario ex is the first challenger stepping up.
