Propagator Drone + Earthcraft + Agatha of the Vile Cauldron

Propagator Drone

Earthcraft

Agatha of the Vile Cauldron

How it works

1. Activate a basic Forest by tapping it, adding .
2. Activate Propagator Drone by paying at most 1, creating a 0/1 Eldrazi Spawn creature token.
3. Activate Earthcraft by tapping the Eldrazi Spawn, untapping the basic Forest.
4. If needed, activate the Eldrazi Spawn by sacrificing it, adding C.
5. Repeat.

This clever loop uses Earthcraft to turn your freshly minted token economy into an untap engine, letting you tap the very Eldrazi Spawn you just created to untap a basic Forest. To make this self-sustaining, Agatha of the Vile Cauldron steps in as a master discount artisan, slashing the activation cost of Propagator Drone's ability down to a manageable size so you can churn out creature tokens on demand. Meanwhile, Propagator Drone doesn't just provide the initial bodies; its passive ability also grants your swarm evolve, synergizing nicely with the chaos of endless creature entries, sacrifices, and deaths.
