This clever loop relies on Tuktuk Rubblefort to grant your creatures haste, allowing Dockside Extortionist to immediately rush back onto the battlefield the moment it is cast. As long as your opponents control enough artifacts and enchantments, the Treasure tokens generated by Dockside Extortionist more than pay for its re-casting. This leaves you with enough excess mana to cast Lady Sun, whose activated ability safely bounces both herself and the goblin back to your hand so the cycle can begin anew.
