All of the cards fit the concept, but the AI probably won't be able to use a player-designed deck properly. Especially since they aren't drawing every card in the deck. I think the chances of winning would be rather dependent on luck, as it could either be an almost-mirror-match with one side having twice as many cards or an easy fight with the AI getting only useless cards (he can't mind gate cards you draw with hourglasses or TU/fractal immortal creatures).
The supernovas shouldn't really be needed, using quantum towers in their place will be more stable overall. Though it's probably better to just remove them as otherwise it will be overflowing with towers. More towers can easily be mind gated from any deck.
Also, 12 steals may be too many.
