Based on Contrary's "Mulligan's Mutation", I Thought about the huge difference between Mutation and Improve, so this deck came to my mind.

The idea is that, because of the Mulligan (that's the reason of the name), it's almost impossible to start without 0 cost cards. So well, the rest is self explained: At least 1 Pilar in the 1st turn, Super Nova and stuff in the 2nd and fun granted.
You may have much fun in AI3 and PVP.
