This deck is very similar to the draft I showed in an earlier post.
This deck pilots well in Solitaire, Diregraf Colossus is great early game to generate tokens, or late with a bunch of zombies in your graveyard to add +1/+1 counters on Diregraf Colossus.
There is only one Jace, but if he comes in late game, the card advantage is amazing.
Here I generated many tokens out of Diregraf Colossus.
