• Grub, Storied Matriarch // Grub, Notorious Auntie

What must be in place

You control a creature that has haste and that has toughness 2 or greater.
An opponent cannot block creatures you control.

How to execute it

Breath of Fury triggers, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to the token with haste, then causing you to untap all creatures you control and to get an additional combat phase after this one.
3. Move to your next combat phase, and declare Grub and the token that has Breath of Fury attached as attackers.
4. Grub triggers, putting a -1/-1 counter on the creature with Breath of Fury attached, and then creating a tapped and attacking copy of that creature.
5. Repeat from step 2.
