Pitiless Plunderer + Eternal Witness + Mitotic Slime + Nethroi, Apex of Death + Thermopod

Pitiless Plunderer

Eternal Witness

Mitotic Slime

Nethroi, Apex of Death

Thermopod

How it works

1. Cast Nethroi for its mutate cost by paying 4G/W, putting it on top of a non-Human creature you control.
2. When Nethroi enters the battlefield, it triggers.
3. Holding priority, activate Thermopod's second ability by sacrificing Nethroi, adding .
4. When Nethroi dies, Pitiless Plunderer triggers, creating a Treasure artifact token.
5. Resolve the Nethroi trigger from step 2, returning Eternal Witness and Mitotic Slime from your graveyard to the battlefield.
6. When Eternal Witness enters the battlefield, it triggers, returning Nethroi from your graveyard to your hand.
7. Activate Thermopod's second ability twice by sacrificing Eternal Witness and Mitotic Slime, adding .
8. When Eternal Witness and Mitotic Slime die, Pitiless Plunderer triggers twice and Mitotic Slime triggers once.
9. Resolve both Pitiless Plunderer triggers, creating two Treasure artifact tokens.
10. Resolve the Mitotic Slime trigger, creating two 2/2 Ooze creature tokens.
11. Activate Thermopod's second ability by sacrificing an Ooze, adding .
12. When the Ooze dies, it and Pitiless Plunderer trigger.
13. Resolve the Pitiless Plunderer trigger, creating a Treasure artifact token.
14. Resolve the Ooze trigger, creating two 1/1 Ooze creature tokens.
15. Activate three Treasures by tapping and sacrificing them, adding G/W.
16. Repeat.

This intricate loop starts by leveraging Nethroi, Apex of Death's mutate trigger to pull both Eternal Witness and Mitotic Slime straight from your graveyard onto the battlefield. Thermopod acts as the core sacrifice outlet, turning every sacrificed creature into vital red mana while simultaneously letting Nethroi hit the graveyard so it can be reclaimed. Meanwhile, Pitiless Plunderer watches the carnage unfold, steadily converting every single death into a valuable Treasure token. As Mitotic Slime collapses into smaller and smaller Ooze tokens, they feed right back into Thermopod and Pitiless Plunderer, while Eternal Witness continuously returns Nethroi to your hand to restart the entire cascade.
