>>42398878252 Atk Life Orb Cinderace U-turn vs. 252 HP / 252+ Def Grimmsnarl: 45-55 (22.2 - 27.2%) -- 36% chance to 4HKO
If you u-turn, you'll just give more turns for grimmsnarl to setup screens, then change into something that can buff/swap your team since even a wet paper is more bulky than cinderace.
(Because of shiters like you that smogon banned dynamax)
