Cold Storage + Dockside Extortionist + Restoration Gearsmith

Cold Storage

Dockside Extortionist

Restoration Gearsmith

How it works

1. Activate Cold Storage's first ability twice by paying 6, exiling Restoration Gearsmith and Dockside Extortionist from the battlefield.
2. Activate Cold Storage by sacrificing it, returning Dockside Extortionist and Restoration Gearsmith from exile to the battlefield.
3. When Dockside Extortionist and Restoration Gearsmith enters the battlefield, they trigger.
4. Resolve the Dockside Extortionist trigger, creating at least ten Treasure artifact tokens.
5. Resolve the Restoration Gearsmith 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 transforms a dense board of opponent's artifacts and enchantments into an endless engine of value, requiring opponents to control at least eleven such permanents to fuel the loop. By using Cold Storage's ability to safely store your key threats in exile, you set up a explosive sequence where sacrificing the artifact unloads both Dockside Extortionist and Restoration Gearsmith simultaneously. Dockside Extortionist floods your side of the table with a massive influx of Treasure tokens, while Restoration Gearsmith smoothly fishes Cold Storage back out of your graveyard to hand so you can recast and reset the whole process.
