Volrath, the Shapestealer + Grim Poppet + Hapatra, Vizier of Poisons

Volrath, the Shapestealer

Grim Poppet

Hapatra, Vizier of Poisons

How it works

1. Activate Volrath by paying 1, causing it to become a copy of Grim Poppet until your next turn.
2. Activate Grim Poppet by removing a -1/-1 counter from it, putting a -1/-1 counter on Volrath.
3. Hapatra triggers, creating a creature token.
4. Activate Volrath by removing a -1/-1 counter from it, putting a -1/-1 counter on Grim Poppet.
5. Hapatra triggers, creating a creature token.
6. Repeat from step 2.

By paying just one mana to turn Volrath, the Shapestealer into a copy of Grim Poppet, you unlock a clever loop of mutual counter-shifting between the two creatures. Because Volrath retains its copy ability, you can continuously strip and replace -1/-1 counters back and forth between them without ever running out of fuel. Meanwhile, Hapatra, Vizier of Poisons watches this microscopic warfare unfold, eagerly generating an endless swarm of deathtouch Snake tokens every single time a counter is placed.
