Why would Ursaring use Trash when he has Facade to work with?Thunder Wave hits Grounds? Fuck yeah, Poison Heal Gliscor, immune to another status. Seems like they're really powering up a lot of old moves.
Ursaring with Guts STAB Thrash may be cool too.
Thunder Wave is obviously the big one, but the new Lightningrod will prevent folks from just spamming TWaves I recon.
