Propagator Drone + Earthcraft + Doubling Season

Propagator Drone

Earthcraft

Doubling Season

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 loop is a masterclass in economic mana-conversion, fueled by the explosive token-doubling power of Doubling Season to turn a mana deficit into a massive surplus. When you activate Propagator Drone's ability, Doubling Season steps in to double your production into two Eldrazi Spawn tokens instead of just one. Those newly minted Eldrazi Spawn tokens can then be immediately tapped via Earthcraft to untap a basic Forest, refunding your green mana while leaving the creatures safely tapped. Finally, sacrificing those same Eldrazi Spawn tokens for their own mana ability yields colorless mana to fund the next activation, netting you an endless stream of death, sacrifice, and entry triggers.
