Mega Blastoise Trick Room Rain

Synergy

Farigiraf sets Trick Room and Rain Dance while Blastoise-Mega uses Fake Out to buy setup time, then fires off Water Spout boosted by rain. Sinistcha provides healing via Hospitality and Life Dew and can reset Trick Room. Kingambit cleans under Trick Room, Tyranitar handles opposing weather, and Choice Scarf Basculegion closes out games once Trick Room expires with Last Respects.
