Agatha's Soul Cauldron + Grist, the Hunger Tide + Grumgully, the Generous

Agatha's Soul Cauldron
Grist, the Hunger Tide
Grumgully, the Generous

Requires
Agatha's Soul Cauldron must be on the battlefield. Grist, the Hunger Tide must be in exile (exiled by Agatha's Soul Cauldron). Grumgully, the Generous must be on the battlefield. Grumgully has at least one +1/+1 counter on it.
Steps
  1. Activate Grumgully 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 Grumgully and repeat the process if the card was an Insect.
  2. The Insect enters the battlefield with a +1/+1 counter on it due to Grumgully, 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.
