Myr Propagator + Mana Echoes + Tannuk, Steadfast Second

Myr Propagator

Mana Echoes

Tannuk, Steadfast Second

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 sequence lets you exponentially multiply your Myr Propagator tokens while generating a growing surplus of colorless mana. As each new token enters the battlefield, Mana Echoes triggers to reward you with a flood of colorless mana based on how many Myrs you control, which more than pays to activate the next token's replication ability. Meanwhile, Tannuk, Steadfast Second ensures your expanding army enters ready for action with haste, while also granting its helpful warp alternative if you ever need to cast your key pieces from exile on a later turn.
