I guess my point was more than we've got so many cantrips which can manipulate the top of our library (brainstorm, ponder, preordain) and lots of high CC cards (Emrakul, Omniscience and Dig Through Time) do we need Enter the Infinite to begin with anyway? Is it realistic enough to cantrip your way into a high cc card on the top of your library in a pinch when you need to go off without hitting your opponent with Emrakul?
