Myr Welder + Biotransference + Empowered Autogenerator + Patrol Signaler

Myr Welder

Biotransference

Empowered Autogenerator

Patrol Signaler

How it works

1. Activate Myr Welder using Empowered Autogenerator's ability by tapping it, putting a charge counter on Myr Welder and adding for each charge counter on Myr Welder.
2. Activate Myr Welder using Patrol Signaler's ability by paying 1 and untapping it, creating a 1/1 Kithkin Soldier creature token.
3. Repeat.

This intricate loop centers on Myr Welder having absorbed Empowered Autogenerator and Patrol Signaler after they were put into the graveyard, granting the construct their activated abilities. Because Biotransference turns Myr Welder and your creature tokens into artifacts, casting or utilizing them synergizes with the engine, though the core execution runs entirely through the welder's newfound toolkit. You tap the welder to add escalating amounts of mana via Empowered Autogenerator's charge counters, then use a portion of that mana alongside Patrol Signaler's untap cost to keep the cycle going. This generates infinite colored mana, infinite charge counters on the welder, and an endless army of tokens.
