Stormcore Bleubling

When Stormcore Bleubling enters the battlefield, contrive 3 (Look at the top three cards of your library. Exile one of them, then put the rest on top in any order. Until end of turn, you may play that card.)
Whenever you cast a spell from exile, Stormcore Bleubling gets +2/+0 and gains haste until end of turn.
