Grub, Storied Matriarch // Grub, Notorious Auntie + Glasspool Mimic // Glasspool Shore + Agatha's Soul Cauldron + Civilized Scholar // Homicidal Brute

Grub, Storied Matriarch // Grub, Notorious Auntie

Glasspool Mimic // Glasspool Shore

Agatha's Soul Cauldron

Civilized Scholar // Homicidal Brute

How it works

1. Cast Glasspool Mimic by paying 2. Choose to have it enter as a copy of Grub, Storied Matriarch.
2. Put Grub, Storied Matriach into your graveyard due to the legend rule.
3. When Glasspool Mimic enters, it triggers, returning Grub, Storied Matriarch from your graveyard to your hand.
4. Activate Agatha's Soul Cauldron by tapping it and exiling Civilized Scholar from your graveyard, putting a +1/+1 counter on Glasspool Mimic.
5. Activate Glasspool Mimic using Civilized Scholar's ability by tapping it, causing you to draw a card and discard Grub, Storied Matriarch. Glasspool Mimic will then untap itself and transform, but it will transform again into Grub, Storied Matriarch.
6. Glasspool Mimic triggers, returning Grub, Storied Matriarch from your graveyard to your hand.
7. Repeat from step 5.
