Myr Welder + Seedcradle Witch + Nyx Lotus

Myr Welder

Seedcradle Witch

Nyx Lotus

How it works

1. Activate Myr Welder using Nyx Lotus's ability by tapping it, adding at least G/WG/WG/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.

This fascinating loop turns **Myr Welder** into a self-sustaining engine by utilizing its ability to inherit the activated traits of exiled artifacts. Once **Nyx Lotus** has been exiled by the Welder, it gains the Lotus's high-devotion tap ability to generate massive amounts of green or white mana. You then channel that surplus into **Seedcradle Witch**, whose active untap ability revitalizes **Myr Welder** so it can tap again for an even greater profit. Because the Witch's mana cost is easily covered by the massive devotion payoff, you loop the sequence to pump out infinitely large creatures alongside boundless colored mana.
