How it works
Gain life in any way.
Cleric Class triggers, putting a +1/+1 counter on Herd Baloth.
Herd Baloth triggers, creating a creature token that enters the battlefield as an artifact due to Encroaching Mycosynth.
Pactdoll Terror triggers, causing you to gain life.
Repeat from step 2.
This loop turns a single initial instance of lifegain into a self-sustaining engine by transforming your entire board into a machine of mutual triggers. With **Encroaching Mycosynth** actively making all your nonland permanents and tokens into artifacts, **Herd Baloth** and **Pactdoll Terror** speak a shared language where every single counter placed leads directly to a new token entering the battlefield. That token entry immediately commands **Pactdoll Terror** to drain your opponents and gain you life, which in turn feeds **Cleric Class** to pump more counters back onto **Herd Baloth**.
