Ok, if not for ray with dragon burst do you guys think it could be used with blastoise/archie for any other type that doesn't have a blastoiseish thing going for it like grass?
Well, to be honest, everything has some sort of accelerator/manipulator, in Expanded at least. Fire has Emboar, Water has Blastoise, Grass has Sceptile PRC, Dark has Hydreigon, Dark Patch and Yveltal XY; Fighting has Landorus FuF + other similar attackers, Electric had Eels, Fairy has Aromatisse, Metal has Bronzong and Psychic has Gardevoir NXD. When you consider all of that, it often is better to go with the specific accelerator/manipulator instead of Blastoise/Archie/Smeargle, which is likely less consistent.
