This clever loop relies on Tannuk, Steadfast Second to grant artifact and red creature cards warp, allowing you to cast Dockside Extortionist from your hand repeatedly as long as your opponents control enough artifacts and enchantments to fund its entry. Each time Dockside Extortionist hits the battlefield, it generates a windfall of Treasure tokens to keep your mana supply flowing. You then cast Lady Sun and immediately tap her ability—boosted by Tannuk, Steadfast Second giving her haste so she doesn't suffer from summoning sickness—to bounce both herself and the goblin back to your hand. By replaying Dockside Extortionist and Lady Sun over and over, you turn their endless coming-and-going into an infinite engine for storm count, sacrifices, and colored mana.
