Pactdoll Terror + Light of Promise + Herd Baloth + Mycosynth Lattice

Pactdoll Terror

Light of Promise

Herd Baloth

Mycosynth Lattice

How it works

1. Gain life in any way.
2. Herd Baloth triggers, putting a +1/+1 counter on itself.
3. Herd Baloth triggers, creating a creature token that enters the battlefield as an artifact due to Mycosynth Lattice.
4. Pactdoll Terror triggers, causing you to gain life.
5. Repeat from step 2.

This intricate loop transforms a simple life-gain event into an explosive cascade, all anchored by Mycosynth Lattice turning every permanent on the battlefield into an artifact. Once the Lattice is in place, Light of Promise ensures that any initial lifegain turns into +1/+1 counters on Herd Baloth, which in turn spawns a 4/4 green Beast creature token. Because of Mycosynth Lattice, that newly minted token enters as an artifact, which immediately triggers Pactdoll Terror to drain your opponent and hand you back more life. That fresh chunk of life feeds right back into Light of Promise, keeping the vicious cycle spinning to generate infinite creature tokens, counters, and lifegain triggers.
