Agatha's Soul Cauldron
Grist, the Hunger Tide
Railway Brawler

   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 Railway Brawler on the battlefield.
You control a creature that has a +1/+1 counter on it.

   Steps

How does this combo work?
1
Activate a creature 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 the creature and repeat the process if the card was an Insect.
2
When the Insect enters, Railway Brawler triggers, putting a +1/+1 counter on the Insect. This causes it to gain Grist's abilities due to Agatha's Soul Cauldron.
3
Repeat from step 1 using the Insect token instead.
