Myr Propagator + Mana Echoes + Concordant Crossroads

Myr Propagator

Mana Echoes

Concordant Crossroads

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 loop is a beautiful geometric explosion of Myrs, fueled entirely by the harmonic resonance of Mana Echoes. Because Concordant Crossroads grants haste to all creatures, your newly birthed tokens don't have to wait around to join the choir. Each activation of Myr Propagator brings a fresh token onto the battlefield, instantly increasing the shared creature count for Mana Echoes to turn into an ever-growing surplus of colorless mana.
