Propagator Drone + Earthcraft + Training Grounds

Propagator Drone

Earthcraft

Training Grounds

How it works

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

This elegant little loop turns Propagator Drone into an absolute token factory by cutting down its activation cost to a manageable {1}{G} with the help of Training Grounds. Once you have a basic Forest in play, Earthcraft steps in to effortlessly refund your mana by letting the freshly minted 0/1 Eldrazi Spawn tap to untap the land right after it enters. You can then sacrifice that same Eldrazi Spawn for colorless mana to complete the cycle, netting an endless stream of sacrifice, death, and entry triggers to fuel your strategy.
