Slimefoot and Squee + Pitiless Plunderer + Altar of Dementia

Slimefoot and Squee

Pitiless Plunderer

Altar of Dementia

How it works

1. Activate Altar of Dementia twice by sacrificing the persist or undying creature and Slimefoot and Squee.
2. When Slimefoot and Squee and the other creature die, Pitiless Plunderer triggers twice and the other creature's persist or undying ability triggers.
3. Resolve the Pitiless Plunderer triggers, creating two Treasure artifact tokens.
4. Resolve the persist or undying trigger, returning the creature from your graveyard to the battlefield with either a -1/-1 or +1/+1 counter on it.
5. Activate Altar of Dementia by sacrificing the undying or persist creature.
6. When the creature dies, Pitiless Plunderer triggers, creating a Treasure token.
7. Resolve the Altar of Dementia ability.
8. Activate the Treasures by tapping and sacrificing them, adding .
9. Activate Slimefoot and Squee by paying 1 and sacrificing a Saproling.
10. When the Saproling dies, Pitiless Plunderer triggers, creating a Treasure artifact token.
11. Resolve the Slimefoot and Squee ability, returning it and the persist or undying creature from your graveyard to the battlefield.
12. When Slimefoot and Squee enters, it triggers, creating a 1/1 Saproling creature token.
13. Activate a Treasure by tapping and sacrificing it, adding 1.
14. Repeat.

This loop transforms a graveyard into an endless engine of sacrifice and resurrection, fueled by Pitiless Plunderer to turn every death into a refund of mana. You begin by grinding away creatures with Altar of Dementia, which naturally triggers Pitiless Plunderer to generate the Treasure tokens needed to pay for everything. Slimefoot and Squee acts as the ultimate recursive engine, bringing itself and another creature back from the dead while its own entry triggers a fresh 1/1 green Saproling token to feed the next cycle.
