Nethroi, Apex of Death + Phyrexian Altar + Mitotic Slime + Spider-Man 2099, Miguel O'Hara

Nethroi, Apex of Death

Phyrexian Altar

Mitotic Slime

Spider-Man 2099, Miguel O'Hara

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 Spider-Man 2099 and Mitotic Slime from your graveyard to the battlefield.
3. When Spider-Man 2099 enters, it triggers, returning Nethroi from the battlefield to your hand.
4. Activate Phyrexian Altar twice by sacrificing Spider-Man 2099 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 clever loop centers around Nethroi, Apex of Death, whose mutate trigger reaches deep into your graveyard to pull back Mitotic Slime and Spider-Man 2099 whenever it enters the fray. As Spider-Man 2099 bounces Nethroi back to your hand, Phyrexian Altar provides the sacrifice outlet to dismantle your board for mana while triggering Mitotic Slime's cascading trail of Ooze tokens. Those tokens feed right back into Phyrexian Altar to cover the remaining costs and fuel the entire engine, generating infinite mana, tokens, and death triggers along the way.
