Grim Poppet + Mirror Image + Hapatra, Vizier of Poisons

Grim Poppet

Mirror Image

Hapatra, Vizier of Poisons

How it works

1. Activate Grim Poppet by removing a -1/-1 counter from it, putting a -1/-1 counter on Mirror Image.
2. Hapatra triggers, creating a creature token.
3. Activate Mirror Image 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 loop is a masterclass in recycling counters, turning back-and-forth erosion into a literal nest of vipers. By leveraging the activated ability of Grim Poppet to strip a counter from itself and place it onto Mirror Image—which has entered as a copy of Grim Poppet—we set up a reciprocating engine of decay. Every single time a -1/-1 counter is shifted onto either creature, Hapatra, Vizier of Poisons watches over the process and rewards your morbid resourcefulness by churning out a steady stream of 1/1 green Snake creature tokens with deathtouch. You can endlessly reverse the process by having Mirror Image remove its own counter to place one back on Grim Poppet, ensuring Hapatra's triggers never stop firing.
