Mana Echoes + Propagator Drone + Chromatic Orrery

Mana Echoes

Propagator Drone

Chromatic Orrery

How it works

1. Activate Propagator Drone by paying 4, creating a 0/1 Eldrazi Spawn creature token.
2. When the Eldrazi Spawn enters, Mana Echoes triggers, adding C for each Eldrazi and Spawn you control.
3. Repeat.

This clever loop kicks into gear once you activate Propagator Drone's ability to manufacture a fresh 0/1 Eldrazi Spawn token, which immediately catches the attention of Mana Echoes. Because the newly minted Spawn shares creature types with your growing army, Mana Echoes floods your mana pool with an escalating wave of colorless mana that quickly turns net-positive. You can then tap Chromatic Orrery to filter that colorless treasure trove into any color of mana you might need while simultaneously using its massive card-drawing activation to unearth victory from your deck.
