Dockside Extortionist + Corpse Dance + Altar of Dementia

Dockside Extortionist

Corpse Dance

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. Cast Corpse Dance with buyback by paying 4, returning Dockside Extortionist from your graveyard to the battlefield, and then returning Corpse Dance to your hand.
3. When Dockside Extortionist enters the battlefield, it triggers, creating at least five Treasure tokens.
4. Activate five Treasures by tapping and sacrificing them, adding 4.
5. Repeat.
6. If opponents control at least six artifacts and/or enchantments, this combo nets infinite Treasure tokens and colored mana.

This loop relies on recycling Dockside Extortionist over and over to continuously harvest Treasure tokens, provided your opponents control enough artifacts and enchantments to fuel the loop's mana cost. Each time Dockside Extortionist enters the battlefield, its triggered ability funds the casting of Corpse Dance, which brings it right back from the graveyard with its buyback cost returning the spell safely to your hand. Meanwhile, Altar of Dementia acts as the sacrifice outlet that puts the goblin back into the graveyard while simultaneously milling your opponents out through an endless cycle of death and resurrection.
