I like the idea of transmute to Meddling. I'll have to try that out, or I'm thinking about Surgical Extraction takes care of both issues hitting griz or open the vaults.

I'd try both. Surgical Extraction is pretty good card in my opinion. It can help against other decks as well.

(cough cough) Thing in the Ice (cough cough)

It's better to lock down your opponent while he has no creatures, I guess... Also, isochron scepter trigers the Thing ;)

Maybe getting back Myth Realized? It synergyses well with it too :D

It's a good idea for sure. Only problem is it gives the deck a weakness it usually doesn't have; creature removal. I will consider it for the sb though
