Grimmsnarl

Grimmsnarl's Prankster ability grants +1 priority to all non-attacking moves, allowing it to reliably set Light Screen and Reflect before the opponent can act. Light Clay extends screen duration from 5 to 8 turns, giving the team more setup time. Parting Shot is the key enabler: used on Staraptor, it gives Staraptor a +1 Attack and Special Attack boost as a partner pivot. Careful nature with 31 HP, 20 Def, and 15 SpD investment gives it enough bulk to absorb hits while performing its support role across multiple turns.
