Myr Welder + Encroaching Mycosynth + Empowered Autogenerator + Gilder Bairn

Myr Welder

Encroaching Mycosynth

Empowered Autogenerator

Gilder Bairn

How it works

1. Activate Myr Welder using Empowered Autogenerator's ability by tapping it, putting a charge counter on Myr Welder and adding or for each charge counter on Myr Welder.
2. Activate Myr Welder using Gilder Bairn's ability by paying 2G/U and untapping it, targeting any permanent.
3. Repeat.

This clever machinery transforms Myr Welder into an explosive engine by utilizing Encroaching Mycosynth to treat it as an artifact, granting it the activated abilities of every piece in the graveyard. Once Empowered Autogenerator is exiled to fuel its imprints, the welder gains the power to accumulate charge counters and generate escalating amounts of colored mana. By also absorbing Gilder Bairn's ability, you can pay to untap the welder while exponentially doubling those very same charge counters, leaving you with boundless mana and infinitely scaling power.
