Grim Poppet + Hapatra, Vizier of Poisons + Vizier of Many Faces

Grim Poppet

Hapatra, Vizier of Poisons

Vizier of Many Faces

How it works

1. Activate Grim Poppet by removing a -1/-1 counter from it, putting a -1/-1 counter on Vizier of Many Faces.
2. Hapatra triggers, creating a creature token.
3. Activate Vizier of Many Faces by removing a -1/-1 counter from it, putting a -1/-1 counter on Grim Poppet.
4. Hapatra triggers, creating a creature token.
5. Repeat.

This clever loop revolves around a perpetual redistribution of counters between Grim Poppet and a clone of it made by Vizier of Many Faces, creating a self-sustaining engine. Because Grim Poppet enters the battlefield with three -1/-1 counters, and Vizier of Many Faces can enter as a copy of it, you have two creatures capable of pinging each other to pass counters back and forth indefinitely. Hapatra, Vizier of Poisons watches this entire exchange from the sidelines, happily turning every single counter placement into an army of 1/1 green Snake creature tokens with deathtouch.
