Myr Welder + Umbral Mantle + Sisay's Ring

Myr Welder

Umbral Mantle

Sisay's Ring

How it works

1. Activate Myr Welder using Sisay's Ring's ability by tapping it, adding at least .
2. Activate Umbral Mantle by paying , untapping Myr Welder.
3. Repeat.

This ingenious loop turns **Myr Welder** into a self-contained mana and pump engine by leveraging the artifact-exiling power of its imprint ability to steal text from the graveyard. Once **Sisay's Ring** is safely in exile beneath it, the Welder gains the ability to tap for two colorless mana, leaving a net profit after paying the three-mana untap cost of **Umbral Mantle**. Because the Mantle can also be activated repeatedly by pumping in that surplus mana, you can infinitely grow your creature's stats while generating boundless colorless mana.
