What's the best way for offense to handle Groundceus? Kyogre's set up bait for Primal Don and Palkia can't easily switch in.
Idk about the best but Giratina-O can kind of check Dragon Claw variants but non SD with a DM, Ho-Oh does OK if it's lacking Rock Slide, Arceus Ground also checks it nicely with Judgement, Mega Rayquaza can check it if it doesn't have an SD up. Mega Mence can set up on non SD variants with the help of Intimidate, Base Groudon does well against Fire Punch instead of Overheat variants, Ditto can revenge it I guess. You can also use Lugia. That's all I can really think of right now.
