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

Pitiless Plunderer

Eternal Witness

Mitotic Slime

Nethroi, Apex of Death

Phyrexian Altar

How it works

1. Cast Nethroi either from your hand or from the command zone for its mutate cost by paying 4G/W plus commander tax, if applicable, putting it on top of a non-Human creature you control.
2. When Nethroi enters the battlefield, it triggers.
3. Holding priority, activate Phyrexian Altar by sacrificing Nethroi, adding one mana of any color.
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 Phyrexian Altar by sacrificing Eternal Witness and Mitotic Slime, adding two mana of any color.
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 Phyrexian Altar by sacrificing two Oozes, adding two mana of any color.
12. When the Oozes die, they each trigger and Pitiless Plunderer triggers twice.
13. Resolve both Pitiless Plunderer triggers, creating two Treasure artifact tokens.
14. Resolve both Ooze triggers, creating four 1/1 Ooze creature tokens.
15. Activate Phyrexian Altar twice by sacrificing two Oozes, adding two mana of any color.
16. When the Oozes die, Pitiless Plunderer triggers twice, creating two Treasure artifact tokens.
17. Activate the seven Treasures by tapping and sacrificing them, adding 4G/W.
18. Repeat.

This intricate loop uses Nethroi, Apex of Death's explosive mutate trigger to pull Eternal Witness and Mitotic Slime straight from your graveyard, recycling Nethroi right back to your hand in the process. Phyrexian Altar acts as the sacrificial engine that turns your creatures into the necessary mana, while Pitiless Plunderer converts every single death—including the cascading generations of ooze tokens born from Mitotic Slime—into a steady stream of Treasure tokens. By repeatedly sacrificing the original crew and their multiplying spawn to the Altar, you generate a massive surplus of mana and triggers to fuel your victory.
