Nethroi, Apex of Death + Phyrexian Altar + Mitotic Slime + Ancestral Statue

Nethroi, Apex of Death

Phyrexian Altar

Mitotic Slime

Ancestral Statue

How it works

1. Cast Nethroi either from your hand or from the command zone for its mutate cost by paying 4G/W, putting it under a non-Human creature you control.
2. Nethroi triggers, returning Ancestral Statue and Mitotic Slime from your graveyard to the battlefield.
3. When Ancestral Statue enters, it triggers, returning Nethroi from the battlefield to your hand.
4. Activate Phyrexian Altar twice by sacrificing Ancestral Statue and Mitotic Slime, adding .
5. When Mitotic Slime dies, it triggers, creating two 2/2 Ooze creature tokens.
6. Activate Phyrexian Altar twice by sacrificing the Oozes, adding 1G/W.
7. When the Oozes die, they trigger, creating four 1/1 Ooze creature tokens.
8. Activate Phyrexian Altar three times by sacrificing three Oozes, adding 3.
9. Repeat.

This elegant loop lets Nethroi, Apex of Death endlessly exploit the graveyard by repeatedly mutating onto the battlefield, fueled entirely by the mana and sacrifices provided by Phyrexian Altar. Each iteration is jump-started by Nethroi's mutate trigger pulling Ancestral Statue and Mitotic Slime back from the dead, where Ancestral Statue's entry trigger bounces Nethroi right back to your hand so it can be recast. Meanwhile, the demise of Mitotic Slime and its cascading stream of smaller Ooze tokens provides all the necessary fodder for Phyrexian Altar to churn out a surplus of colored mana, keeping the entire engine running indefinitely.
