Flip a coin. If tails, this Pokémon also does 60 damage to itself.
Mega Heracross ex wins by slamming Dynamic Horn for 170 damage, reaching near or full one-shots on every Pokemon in the format, while Serperior's support sustains the attack chain. One flip of tails deals 60 recoil to itself, so the deck is built around surviving and negating that self-damage.
Open with Heracross active and Snivy on the bench; use Poké Ball for Snivy and Rare Candy to skip Servine and get Serperior into play quickly. Serperior provides recovery or Energy benefits that enable Mega Heracross ex to keep swinging. Once Heracross evolves into Mega Heracross ex, load four Energy and fire Dynamic Horn — 170 damage claims one-shots on nearly every non-Mega target and scores 2 points on ex Pokemon. Leaf Cape reduces recoil or incoming damage, and Erika and Lyra provide healing for tails outcomes. Cyrus redirects threats during setup, and Teal Mask Ogerpon ex handles matchups where a secondary attacker is needed.

Dynamic Horn base 170 (heads) = 1-shot on most ex Pokemon
Tails result adds 60 recoil to Mega Heracross ex; Leaf Cape and Erika mitigate self-damage
Use Rare Candy on Snivy to skip Servine and get Serperior in play as early as turn 2 or 3. Serperior is a Stage 2 that cannot be fetched by Poké Ball, so Professor's Research and Copycat must find it through draw. Once Serperior is up, its support enables Mega Heracross ex to keep attacking across multiple turns despite the recoil risk.
Leaf Cape reduces incoming or recoil damage for Mega Heracross ex, keeping it above KO range after a tails Dynamic Horn. Erika heals your Pokemon to erase accumulated recoil between attacks. May provides item search to find Leaf Cape quickly. Lyra adds an additional healing layer. Any tails that brings Mega Heracross ex near 0 HP is an instant game loss, so this protection layer is mandatory.
Mega Heracross ex is a Grass type, which carries Fire weakness. Emboar, Blacephalon ex, and other Fire attackers hit it for double damage, potentially one-shotting the 180-HP Mega before it can swing. Tournament data confirms Emboar holds a 75% win rate against this archetype — running a Fire attacker is the most direct counter.
Mega Heracross ex takes 60 recoil on tails and has 180 HP. If it flips tails twice without healing, it enters KO range. Use Rocky Helmet to add recoil on your active Pokemon so Mega Heracross ex takes 60 recoil plus chip damage from your tool on the same turn, compressing the HP deficit faster than Erika or Lyra can recover.
Mega Heracross ex cannot attack until fully evolved and four Energy are attached. Heracross is a Basic before the Mega form, meaning Poké Ball cannot retrieve the Mega evolution and it must be drawn naturally. Attacking Heracross aggressively before the Mega appears forces a one-turn delay and possibly loses Mega Heracross ex's only copy, a game-ending outcome.
