Nethroi, Apex of Death + Phyrexian Altar + Mitotic Slime + Ambrosia Whiteheart

Nethroi, Apex of Death

Phyrexian Altar

Mitotic Slime

Ambrosia Whiteheart

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 Ambrosia Whiteheart and Mitotic Slime from your graveyard to the battlefield.
3. When Ambrosia Whiteheart enters, it triggers, returning Nethroi from the battlefield to your hand.
4. Activate Phyrexian Altar twice by sacrificing Ambrosia Whiteheart 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 intricate loop centers around Nethroi, Apex of Death, whose mutate trigger plucks both Ambrosia Whiteheart and Mitotic Slime straight from your graveyard to the battlefield. As Ambrosia Whiteheart enters the fray, its ability bounces Nethroi right back to your hand so you can mutate it all over again, while Phyrexian Altar provides the mana engine by turning your disposable creatures into currency. Sacrificing Ambrosia Whiteheart and Mitotic Slime—followed by the cascading wave of 2/2 and 1/1 Ooze tokens they leave behind—generates more than enough mana to recast Nethroi, fueling an endless cycle of recursion, tokens, and sacrifices.
