This is a combo deck. Get Treasure Hunt in your opening hand, use it to get more Treasure Hunt or Zombie Infestation, then spam tokens. Contested War Zone is some cheap buff and Reliquary Tower protects you if you don't find a Zombie Infestation the first time. Vault of the Archangel brings insane lifegain if you can get the colors right.

Don't be afraid to mulligan AGGRESSIVELY. Obviously you could mull to 1 and still win, because you WILL draw the land you need.
