Propagator Drone + Earthcraft + Primal Vigor

Propagator Drone

Earthcraft

Primal Vigor

How it works

1. Activate a basic Forest by tapping it, adding .
2. Activate Propagator Drone by paying 3, creating two 0/1 Eldrazi Spawn creature tokens.
3. Activate Earthcraft by tapping an Eldrazi Spawn, untapping a basic Forest.
4. Activate the basic Forest by tapping it, adding .
5. Activate Earthcraft by tapping an Eldrazi Spawn, untapping the basic Forest.
6. Activate the Eldrazi Spawns by sacrificing them, adding CC.
7. Repeat.

This clever loop turns the steady token-making of Propagator Drone into a self-sustaining engine by relying on Earthcraft to tap your newly created Eldrazi Spawn, untapping a basic land to keep the green mana flowing. Meanwhile, Primal Vigor supercharges the sequence by doubling every token created, ensuring you generate an excess of Eldrazi Spawn to fuel both the land-untapping and subsequent sacrifices. Because you're constantly spawning extra bodies, you have more than enough fodder to repeat the process indefinitely, generating boundless enters-the-battlefield, death, and sacrifice triggers.
