Dockside Extortionist + Lady Sun + Hammer of Purphoros

Dockside Extortionist

Lady Sun

Hammer of Purphoros

How it works

1. Cast Dockside Extortionist by paying 1.
2. When Dockside Extortionist enters the battlefield, it triggers, creating at least five Treasure artifact tokens.
3. Activate five Treasures by tapping and sacrificing them, adding 2.
4. Cast Lady Sun by paying 1.
5. Activate Lady Sun by tapping it, returning it and Dockside Extortionist from the battlefield to your hand.
6. Repeat.

This looping engine relies on the interplay of Dockside Extortionist and Lady Sun to generate an endless cycle of enters-the-battlefield and leave-the-battlefield triggers, provided your opponents control enough artifacts and enchantments to fund the loop. Each iteration starts when Dockside Extortionist enters the battlefield to spawn a windfall of Treasure tokens, which you sacrifice to float the mana needed to recast both the goblin and Lady Sun. Lady Sun then uses her activated ability to bounce herself and the Extortionist back to your hand, resetting the board so you can cast them again. Meanwhile, Hammer of Purphoros sits quietly on the battlefield, ensuring that any hasty creature tokens you might care to make can join the fray, though the true magic here is the self-sustaining mana and artifact loop that leaves your opponents buried under endless treasures.
