Grimmsnarl

Grimmsnarl is the team's dedicated support piece, using Prankster priority to get Light Screen and Reflect up before faster threats can punish the setup turn. Careful with heavy HP and mixed defensive investment lets it soak special and physical hits alike long enough to keep casting screens. Foul Play turns an opposing attacker's own high Attack stat against them, so it hits hardest against exactly the threats this team otherwise struggles to answer. Parting Shot cycles it out safely into Tyranitar or Mega Metagross while still chipping the opponent's offensive stats. Roseli Berry blunts a Fairy-type hit on the way in.
