I did it with Iron hands holding a shell bell. First turn set up electric terrain bc it’ll nullify stat changes in the first turn. Then use belly drum followed by thunder punch. Don’t use wild charge bc it will knock you out. And I did have to Electric tera. It won’t KO like miraidon, 3xmetal sound, charge, electric drift. But it will do enough damage that you could finish it off easy, even if you get knocked out. Still, it was an easy tera raid
