Ashnod the Uncaring + Bonecaller Cleric + Dockside Extortionist + Carrion Feeder

Ashnod the Uncaring

Bonecaller Cleric

Dockside Extortionist

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing Dockside Extortionist.
2. Ashnod the Uncaring triggers, copying Carrion Feeder's ability.
3. Resolve both Carrion Feeder abilities, putting two +1/+1 counters on Carrion Feeder.
4. Activate Bonecaller Cleric by paying 3 and sacrificing it, targeting Dockside Extortionist.
5. Ashnod the Uncaring triggers, copying Bonecaller Cleric's ability, with the copy targeting Bonecaller Cleric.
6. Resolve both Bonecaller Cleric abilities, returning it and Dockside Extortionist to the battlefield from your graveyard.
7. When Dockside Extortionist enters the battlefield, it triggers, creating at least three Treasure artifact tokens.
8. Activate three Treasures by tapping and sacrificing them, adding 3.
9. Repeat.
10. If opponents control four or more artifacts and/or enchantments, this combo nets infinite Treasure tokens.

This loop transforms Ashnod the Uncaring into a relentless engine of duplication by leveraging sacrifice costs that target permanents. When you sacrifice Dockside Extortionist to Carrion Feeder, Ashnod copies the sacrifice ability, feeding your Carrion Feeder multiple counters while setting up the graveyard recursion. Bringing everything back is handled by Bonecaller Cleric, whose activation is likewise doubled by Ashnod the Uncaring to simultaneously resurrect both the Cleric itself and the Dockside Extortionist. As long as your opponents control enough artifacts and enchantments, the newly generated Treasure tokens refund the mana needed to keep the cycle spinning infinitely.
