>>42109354nvm this, Claydol has a lot of trick it can do but there are other mons that can do those tricks better in doubles. Maybe you can do weakness policy + Cosmic Power setup team where u support Claydol with a lot of mons and it can be alright.
>>42109303Instead I came up with this pic related set for 3v3 singles, you start of with Grimmsnarl and setup dual screens, then you go for the setup with Claydol and if specific Pokemon gives you a lot trouble, say 5 out of 10 games, then you can adjust, say Mimikyu gives your Claydol trouble, maybe you can slap a ghost resist berry on it or have a team mate that is good against Mimikyu (say scarf Excadrill), or if the Stored Power is not doing enough dmg after 3 Cosmic Powers, you could try Calm Mind + Iron Defense and drop Rest and add Leftovers etc. there are certainly a lot of options for this mon and I think you can find a set that can work if the rest of the team is supporting it well enough.
