This card is really cool, buuuuuut it's priced fairly. I don't think tutor abilities with a fair price cut the mustard in a format where you can get this effect for 1 or 2 mana, even considering the flexibility.
And before someone says "but you said the same thing about Jace," yes, this card would be good as a repeatable effect, but not as a one-shot.
@hierarchnoble I thought EDH had a 10 card wishboard?
That's a house rule. The official site states "Abilities which refer to other cards owned outside the game (Wishes, Spawnsire, Research, Ring of Ma'ruf) do not function in Commander without prior agreement on their scope from the playgroup.", which also holds true for 1v1 on MODO.
@brass-man Not what I meant, although your response shows me that I could have been clearer. What I was trying to say was that, if Extract effects become a legitimate presence in the metagame, this card's enabling a player to hide win cons in the sideboard could be important for some decks.
