Grim Poppet + Hapatra, Vizier of Poisons + Spark Double

Grim Poppet

Hapatra, Vizier of Poisons

Spark Double

How it works

1. Activate Grim Poppet by removing a -1/-1 counter from it, putting a -1/-1 counter on Spark Double.
2. Hapatra triggers, creating a creature token.
3. Activate Spark Double 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 elegant loop revolves around an engine of mutual decay, powered by Grim Poppet and a clone of it generated by Spark Double. Because Spark Double enters as a copy of Grim Poppet without retaining its legendary status, both creatures are equipped with the identical active ability to strip away and redistribute -1/-1 counters back and forth between one another indefinitely. Meanwhile, Hapatra, Vizier of Poisons watches this microscopic warfare unfold, her static trigger rewarding every single placement of a -1/-1 counter by breeding a lethal swarm of 1/1 green Snake creature tokens with deathtouch.
