Where is my library?

This deck is a variation on one I have posted before. It utilizes the transmute ability to make the majority of the cards in the deck interchangable with each other. This should win simply by decking the opponent, but it does have the ability to provide beatdown with Kagemaro, or one of the smaller creatures with Followed Footsteps. Early game should focus on countering the early spells and removing critical cards from their hand with mana leak. Once you get above 4 mana you can be using cranial extraction to remove their key cards. The twincasts can be used to copy and utility spells played by the opponent such as land searching or reanimation, however they are best used in concert with Glimpse the Unthinkable as this can lead to an early game decking. I am hesitant about using Traumatize since the effectivness of this card goes down quickly as the game progresses. In short, hinder their progress early game with light counters and some cheap blockers and aim to deck them. Please give some input
