Myr Welder + Crab Umbra + White Lotus Tile

Myr Welder

Crab Umbra

White Lotus Tile

How it works

1. Activate Myr Welder using White Lotus Tile's ability by tapping it, adding at least
2. Activate Crab Umbra by paying 2, untapping Myr Welder.
3. Repeat.

This clever loop transforms Myr Welder into a self-contained mana engine by using its imprint ability to absorb White Lotus Tile directly from your graveyard. Once it holds the Tile, Myr Welder gains its tap ability to generate a flood of colored mana, which is then funneled straight into Crab Umbra's untap activation. Because Crab Umbra enchants the Welder directly, you can endlessly pay the activation cost to untap the creature, netting infinite colored mana with every single iteration.
