This cunning loop relies on Dockside Extortionist entering the battlefield to flood your board with Treasure tokens, provided your opponents control enough artifacts and enchantments. You can then feed that little Goblin to Thermopod to generate red mana, while sacrificing your Treasures provides the black mana needed to fuel Ruthless Technomancer's reanimation ability. Because Ruthless Technomancer can trade just a single Treasure token to pluck Dockside Extortionist right back out of your graveyard, you generate a surplus of tokens with every single iteration.
