Grim Poppet + Hapatra, Vizier of Poisons + Clone

Grim Poppet

Hapatra, Vizier of Poisons

Clone

How it works

1. Activate Grim Poppet by removing a -1/-1 counter from it, putting a -1/-1 counter on Clone.
2. Hapatra triggers, creating a creature token.
3. Activate Clone 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 turns the mechanical distribution of -1/-1 counters into an endless supply of deathtouch defense, fueled entirely by the synergy between Grim Poppet, Clone, and Hapatra, Vizier of Poisons. By having Clone enter the battlefield as a copy of Grim Poppet, you establish a reciprocating engine where each creature can strip a counter from itself to place one on the other. Every single time a counter is placed in this fashion, Hapatra's static ability triggers to reward you with a 1/1 green Snake creature token with deathtouch. Because the counters can bounce endlessly back and forth between the two Poppets, you generate an infinite loop of creature entry triggers and an unbounded army of venomous serpents.
