Mega Venusaur

Mega Venusaur skips Giga Drain for Sleep Powder because its bulk lets it land the move more than once a game, and per the trainer's own team report it was built largely to shut down Trick Room setters that would otherwise flip the sand plan on its head. Modest with a Speed spread built to outrun a Modest Politoed keeps it relevant even before Mega Evolving, and Chlorophyll offers a bonus Speed tier if the sun ever turns on. Alongside Rotom-Wash, it forms the team's answer to Charizard Y, trading chip damage until the sand-boosted attackers behind it can finish the game.
