Ranshi, Tomebound

+1: Flood target creature an opponent controls. (Put a flood counter on it. It's an Island for as long as it has a flood counter on it.)
0: Shift 3 (Look at the top three cards of your library, then exile any number of them and put the rest on top of your library in any order.)
-1: The next spell you cast this turn has entropic. Then transform Ranshi, Tomebound. (Each permanent you sacrifice while casting it pays for {1}.)
