Myr Propagator + Mana Echoes + Garna, the Bloodflame

Myr Propagator

Mana Echoes

Garna, the Bloodflame

How it works

1. Activate Myr Propagator by paying 3 and tapping it, creating a token copy of it.
2. When the Myr Propagator token enters the battlefield, Mana Echoes triggers, adding C for each Myr you control.
3. Repeat using the Myr Propagator token instead.

This delightful loop relies on the compounding power of Mana Echoes to turn a simple replication into an explosive mana engine. By paying into Myr Propagator's ability, you create a token copy that triggers Mana Echoes, whose explosive burst of colorless mana easily refunds the activation cost with plenty left over to keep the copies marching. Garna, the Bloodflame ties the whole workshop together by granting haste so your newly birthed tokens can act immediately if needed, while her enter-the-battlefield ability ensures any Myrs lost along the way aren't truly gone for good.
