Quote from benjameenbear »Yeah, the new Grixis Commander seems really good, even if it only gives a single card flashback for the turn.
I'd also like to chime in here and support Paradox Engine. It makes mana rocks absurdly good and turns Isochron Scepter into an infinite combo piece with too many cards. My favorite one that I discovered so far was Isochron Scepter, with Reality shift imprinted on it, Paradox Engine, and a Mana Vault. I didn't actually activate it to deck my wife in the game where this came up, because I'm a smart man, but it was gratifying to know that the Scepter has increased in value substantially with the Engine being in the deck.
