This engine relies on turning your opponents' own board state into an endless fountain of mana, provided they control at least five artifacts and enchantments combined. Each time you replay Dockside Extortionist, its entry triggers to flood your board with enough Treasures to comfortably fund the activation cost of Temur Sabertooth. Temur Sabertooth then whisks Dockside Extortionist safely back to your hand, resetting the loop and leaving you with a growing surplus of mana and sacrifice triggers.
