Grist, the Hunger Tide + Agatha's Soul Cauldron + Bloodspore Thrinax

Grist, the Hunger Tide
Agatha's Soul Cauldron
Bloodspore Thrinax

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