Myr Propagator + Mana Echoes + Rising of the Day

Myr Propagator

Mana Echoes

Rising of the Day

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 clever loop starts with your original Myr Propagator on the board, ready to put its replication magic to work. Thanks to Rising of the Day, your tokens won't be plagued by summoning sickness when they arrive, allowing you to activate them immediately (or in subsequent iterations once the chain is rolling). As each new token copy enters the battlefield, Mana Echoes watches and rewards your growing mechanical swarm, generating an escalating avalanche of colorless mana that quickly outpaces the activation cost and yields an infinite supply of tapped Myr Propagator tokens.
