Agatha's Soul Cauldron + Grist, the Hunger Tide + Master Biomancer

Agatha's Soul Cauldron
Grist, the Hunger Tide
Master Biomancer

Requires
Agatha's Soul Cauldron must be on the battlefield. Grist, the Hunger Tide must be in exile (exiled by Agatha's Soul Cauldron). Master Biomancer must be on the battlefield. Master Biomancer has at least one +1/+1 counter on it.
Steps
  1. Activate Master Biomancer using Grist's first loyalty ability by putting a loyalty counter on it, causing you to create a 1/1 Insect creature token and mill a card, and then put a loyalty counter on Master Biomancer and repeat the process if the card was an Insect.
  2. The Insect enters the battlefield with at least three +1/+1 counters on it due to Master Biomancer, causing it to have Grist's abilities.
  3. Repeat from step 1 using the Insect token instead.
Results
Infinite creature tokens. Infinite ETB. Infinite self-mill.
