Myr Propagator + Mana Echoes + Anger

Myr Propagator

Mana Echoes

Anger

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 takes advantage of Mana Echoes to turn a modest cloning activation into a self-sustaining engine, where each new token entering the battlefield generates more than enough colorless mana from Mana Echoes to repeatedly activate Myr Propagator again. Because Anger sits quietly in your graveyard granting haste as long as you control a Mountain, you don't even have to wait to start chaining your activations immediately. The result is an explosive cascade of infinite creature tokens and infinite colorless mana, ready to overwhelm the table the moment you start propagating.
