Reshiram used V-Create! Wait, WHAT??

It also means switching in a Bouncer to block hazards doesn't work, which is really useful, and it means Magic Bounce Giratina can't do what it's meant to.

EDIT: What about some kind of Archeops? It's fast and strong (if really frail) and can use an ability besides Defeatist. I'm not saying I'm dying to use it or anything, I'm mostly wondering how viable it'd be.

Not very, due to the existence of faster and stronger mons, most notably Simple Tail Glow Deoxys-S. Which is fun to use, but often fails. I tried out one with Minimize, Stored Power, Shadowball; it worked, but you HAVE to remove all their Imposters (and Shedinja) before setting up.
