Passimian/Starmie-Mega Huge Power Trick Room

Synergy

Mega Starmie's Huge Power ability transfers to Passimian via Receiver when Starmie faints, turning Passimian into a devastating physical attacker under Trick Room. The team runs four Trick Room setters (Starmie, Sinistcha, Hatterene, Oranguru) for redundancy, with Torkoal as a secondary sweeper and Oranguru's Psychic Terrain boosting Hatterene's Expanding Force.

Win Conditions

Lead Starmie + Passimian, pass Huge Power to Passimian via Receiver after Starmie faints (through Self-Destruct or being KO'd), then sweep under Trick Room with boosted Close Combat. Torkoal's Eruption in sun is a secondary win condition.

Lead Options

Starmie-Mega + Passimian, Sinistcha + Hatterene, Sinistcha + Starmie-Mega, Oranguru + Hatterene

Threats

Weather teams with Milotic that can outlast the TR window, Ghost-types that block Close Combat, Basculegion, and anything that can prevent Trick Room from going up.
