This vicious loop relies on Dockside Extortionist entering the battlefield and generating enough Treasure tokens from your opponents' artifacts and enchantments to fund the entire operation. You then use Altar of Dementia to send Dockside Extortionist straight to the graveyard, setting the stage for Ruthless Technomancer to step in. By paying {2}{B} and sacrificing a single Treasure, Ruthless Technomancer uses its reanimation ability—fueled by the mana you generated—to pull Dockside Extortionist right back out of the graveyard and back onto the battlefield to repeat the carnage.
