Grim Poppet + Nest of Scarabs + Naga Fleshcrafter

Grim Poppet

Nest of Scarabs

Naga Fleshcrafter

How it works

1. Activate Grim Poppet by removing a -1/-1 counter from it, putting a -1/-1 counter on Naga Fleshcrafter.
2. Nest of Scarabs triggers, creating a creature token.
3. Activate Naga Fleshcrafter by removing a -1/-1 counter from it, putting a -1/-1 counter on Grim Poppet.
4. Nest of Scarabs triggers, creating a creature token.
5. Repeat.

This clever loop turns Grim Poppet's counter manipulation into an engine by bouncing -1/-1 counters back and forth between it and Naga Fleshcrafter. As those counters shift, Nest of Scarabs watches the action and rewards every single placement by flooding the board with 1/1 black Insect creature tokens.
