Agatha's Soul Cauldron
Grist, the Hunger Tide
Grumgully, the Generous
1

   Prerequisites

What do I need to start this combo?
Grist in exile (Grist exiled by Agatha's Soul Cauldron in exile).
Agatha's Soul Cauldron and Grumgully on the battlefield.
Grumgully has at least one +1/+1 counter on it.

   Steps

How does this combo work?
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

What do I get from this combo?
Infinite creature tokens
Infinite ETB
Infinite self-mill
