Mega Heracross / Runerigus Trick Room

Synergy

Runerigus sets Trick Room while Heracross protects, creating a free setup turn against opponents unfamiliar with the rare setter. Mega Heracross then sweeps under reversed speed with Skill Link Pin Missile and Rock Blast hitting five times each. Toxapex and Trevenant form a sustain backbone that burns physical threats, stalls with Regenerator and Harvest, and blocks spread moves with Wide Guard. Incineroar provides Fake Out and Intimidate to buy additional setup turns when needed.

Win Conditions

Set Trick Room turn one with Runerigus while Heracross protects, then mega evolve and sweep with five-hit Pin Missile and Rock Blast. Against slower matchups, pivot to Toxapex for toxic stall while chipping with Venoshock and Wide Guard protection.

Lead Options

Mega Heracross + Runerigus, Mega Heracross + Toxapex, Runerigus + Trevenant

Threats

Teams that can prevent Trick Room setup before Runerigus acts are the primary threat. Sneasler and Garchomp pose damage threats before the burn can land, though Runerigus and Trevenant both carry Will-O-Wisp as answers. Opposing Trick Room teams can be played around with Heracross and Toxapex, using Rock Blast into Torkoal and Toxic to start the stall clock.
