This loop turns a simple transmutation into an endless engine of fiery destruction, fueled entirely by the clever synergy between your permanents. By using Unnatural Selection to dynamically rewrite Magmaw's creature type into a Pirate, you enable Malcolm, Keen-Eyed Navigator to recognize its damage as Pirate-born and shower you with Treasure tokens. Thanks to Primal Vigor doubling every single token generated, every sacrifice yields twice the ammunition needed to keep the cycle going. You simply sacrifice those Treasures and other nonland permanents to Magmaw, looping the damage directly into your opponents' faces until they are thoroughly reduced to ash.
