When Abbot of Keral Keep enters the battlefield, exile the top card of your library. Until end of turn, you may play that card.
Card has been doing well at PT Origins in Vancouver. RDW took 1st place.
My favourite card of the set.I think will be modern playable also
Playing this on turn 2 means that only an exiled land card can be played, since you have no mana left. I would consider this a turn 3 or 4 drop.
Biggest decision is if it should be played on turn two or not, playing this before the land drop would be good.
