electriate? is that a thing?

Na, but it's using the idea that every abilit that does that effect ends with -ate. Honestly though it's sounds pretty... eh compared to the others. Also, saying it would be a useless ability is like saying having an electric type move period is useless. That's... not really the case. Regular Explosion is resisted by Ghost as well so, there's that too lol. Ground is defintiely a lot more common though that's for sure. Uesless no, as good as Refrigerate Explode? No.

((which I might add doesn't save Mega-Glalie from being like... RUish at best I think it is?))
