Grenzo, Dungeon Warden + Soldevi Digger + Dockside Extortionist + Altar of Dementia

Grenzo, Dungeon Warden

Soldevi Digger

Dockside Extortionist

Altar of Dementia

How it works

1. Activate Altar of Dementia by sacrificing Dockside Extortionist, causing target player to mill cards equal to Dockside Extortionist's power.
2. Activate Soldevi Digger by paying 2, putting Dockside Extortionist from your graveyard on the bottom of your library.
3. Activate Grenzo by paying 2, putting Dockside Extortionist from the bottom of your library into your graveyard, and then onto the battlefield.
4. Dockside Extortionist enters the battlefield, creating at least four Treasure artifact tokens.
5. Activate four Treasures by tapping and sacrificing them, adding 4.
6. Repeat.
7. If opponents control at least five artifacts and/or enchantments, this combo nets infinite Treasure tokens and colored mana.

This loop turns your graveyard into a revolving door for Dockside Extortionist, provided your opponents control at least five artifacts and enchantments to fund its entry. With Dockside Extortionist generating a surplus of Treasure tokens each time it enters the battlefield, you have more than enough mana to pay for Soldevi Digger's recycling effect and Grenzo, Dungeon Warden's ability to cheat creatures straight from the bottom of your library. Meanwhile, Altar of Dementia sits ready to convert your loop into an alternate win condition by milling out your opponents, making this a brilliantly self-contained engine that loops resources endlessly.
