How it works

  1. Activate Myr Welder using Prismatic Geoscope's ability by tapping it, adding at least 2G/WG/W
  2. Activate Seedcradle Witch by paying 2G/WG/W, untapping Myr Welder and giving it +3/+3 until end of turn.
  3. Repeat.

By imprinting Prismatic Geoscope into Myr Welder, the mechanical heart of this loop is born: Myr Welder gains the Geoscope's domain mana-producing ability, allowing it to tap for a significant influx of colored mana if you control enough basic land types. We then feed that generated mana into Seedcradle Witch's activated ability, which untaps Myr Welder while pumping its stats. Because the mana produced by the imprinted Prismatic Geoscope outpaces the cost required by Seedcradle Witch's untap ability, you can repeat this cycle indefinitely—leaving you with an infinitely large Myr Welder fueled by boundless colored mana.
