Actually on second thought, my version does stand a chance against Primal Groudon 252+ SpA Abomasnow (Mega Hydreigon) Earth Power vs. 252 HP / 200 SpD Primal Groudon: 228-270 (56.4 - 66.8%) -- guaranteed 2HKO 0 SpA Primal Groudon Lava Plume vs. 0 HP / 0 SpD Abomasnow (Mega Hydreigon) in Harsh Sunshine: 88-104 (27 - 32%) -- guaranteed 4HKO (Even less after attack drops from Intimidate)
