In a fit of restlessness over the past few days I have begun to wonder if this little experiment can function both as a Wizard's Tower and a Desert Cube.
Notable design changes include removing the Battlemage and Master cycles in favor of less color intensive creatures, adding Threshold which could be very wacky in a shared graveyard environment, reducing the number of gold cards, and providing a wider variety of lands in place of basics.
Now, really, the only thing to do is start getting some serious reps in to see how this pile plays.
