Slimefoot and Squee + Ruthless Technomancer + Altar of Dementia

Slimefoot and Squee

Ruthless Technomancer

Altar of Dementia

How it works

1. Activate Altar of Dementia twice by sacrificing Slimefoot and Squee and Ruthless Technomancer, causing target player to mill cards equal to their combined power.
2. Activate Slimefoot and Squee by paying 1 and sacrificing a Saproling, returning Slimefoot and Squee and Ruthless Technomancer to the battlefield from your graveyard.
3. When Slimefoot and Squee and Ruthless Technomancer enter the battlefield, they trigger.
4. Resolve the Slimefoot and Squee trigger, creating a 1/1 Saproling creature token.
5. Resolve the Ruthless Technomancer trigger, causing you to sacrifice the nontoken creature with base power eight or greater and create at least eight Treasure artifact tokens.
6. Activate eight Treasures by tapping and sacrificing them, adding 2.
7. Activate Altar of Dementia by sacrificing Slimefoot and Squee, causing target player to mill cards equal to Slimefoot and Squee's power.
8. Activate Slimefoot and Squee by paying 1 and sacrificing a Saproling, returning Slimefoot and Squee and the nontoken creature with base power eight or greater to the battlefield from your graveyard.
9. When Slimefoot and Squee enters the battlefield, it triggers, creating a 1/1 Saproling creature token.
10. Repeat.
11. If the nontoken creature has base power nine or greater, this combo nets infinite Treasure tokens and colored mana.

This intricate recursive engine centers around Slimefoot and Squee, whose activation lets you trade a Saproling token to pull both itself and another creature straight out of your graveyard. By utilizing Altar of Dementia, you weaponize the combined power of your creatures to mill away your library while fueling the loop. Meanwhile, Ruthless Technomancer steps in to recycle those sacrifices into a massive hoard of Treasure tokens, which then provide the exact mana needed to pay for Slimefoot and Squee's resurrection cost over and over again.
