How it works
Activate Myr Welder using Sceptre of Eternal Glory's ability by tapping it, adding at least three mana of any color.
Activate Myr Welder using Staff of Domination's first ability by paying 1, untapping it.
Repeat.
By utilizing Myr Welder's imprint ability to absorb the activated powers of both artifacts, you turn a single creature into an entire mechanical engine. Once the welder holds the keys, Sceptre of Eternal Glory provides the heavy mana generation required to fuel the loop, provided its condition is met. From there, Staff of Domination steps in to untap the welder for a mere one mana, leaving you with a surplus that easily translates into infinite colored mana, card draw, and life.
