Cold Storage + Dockside Extortionist + Warden of the Eye

Cold Storage

Dockside Extortionist

Warden of the Eye

How it works

1. Activate Cold Storage's first ability twice by paying 6, exiling Warden of the Eye and Dockside Extortionist from the battlefield.
2. Activate Cold Storage by sacrificing it, returning Dockside Extortionist and Warden of the Eye from exile to the battlefield.
3. When Dockside Extortionist and Warden of the Eye enters the battlefield, they trigger.
4. Resolve the Dockside Extortionist trigger, creating at least ten Treasure artifact tokens.
5. Resolve the Warden of the Eye trigger, returning Cold Storage from your graveyard to your hand.
6. Activate ten Treasures by tapping and sacrificing them, adding 10.
7. Cast Cold Storage by paying 4.
8. Repeat.
9. If opponents control eleven or more artifacts and/or enchantments, this combo nets infinite Treasure tokens and colored mana.

This clever loop relies on opponents controlling at least eleven artifacts and enchantments so that Dockside Extortionist can single-handedly fund the engine with a massive windfall of Treasure tokens. By using Cold Storage to temporarily exile both the Extortionist and Warden of the Eye—and then sacrificing the artifact to bring them right back—you reset their powerful enter-the-battlefield triggers. Each iteration lets Warden of the Eye retrieve Cold Storage from your graveyard so you can recast it, sustaining a self-contained cycle that generates infinite mana, artifact tokens, and storm count.
