Garchomp

Adamant Choice Scarf with maximized Attack and Speed makes Garchomp the team's fastest attacker and primary early-game threat, forcing opponents to commit speed control resources before the Mega Evolutions reveal. Rock Slide provides spread flinch pressure, Earthquake hits Steel types and Fire resists flanking Charizard, Dragon Claw offers reliable single-target damage, and Stomping Tantrum punishes opponents who block Earthquake. Rough Skin chips contact move users. This set serves the sun core as an aggressive opener and transitions to late-game sweeper after the Mega has softened opposing teams.
