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 Shilgengar by sacrificing Nethroi.
4. When Nethroi dies, Pitiless Plunderer triggers, creating a Treasure artifact token.
5. Resolve the Shilgengar ability
6. Resolve the Nethroi trigger from step 2, returning Eternal Witness and Mitotic Slime from your graveyard to the battlefield.
7. When Eternal Witness enters the battlefield, it triggers, returning Nethroi from your graveyard to your hand.
8. Activate Shilgengar twice by sacrificing Eternal Witness and Mitotic Slime.
9. When Eternal Witness and Mitotic Slime die, Pitiless Plunderer triggers twice and Mitotic Slime triggers once.
10. Resolve both Pitiless Plunderer triggers, creating two Treasure artifact tokens.
11. Resolve the Mitotic Slime trigger, creating two 2/2 Ooze creature tokens.
12. Resolve both Shilgengar abilities
13. Activate Shilgengar twice by sacrificing two Oozes.
14. When the Oozes die, they each trigger and Pitiless Plunderer triggers twice.
