Bramble Sovereign

Mass Hysteria

How it works

1. Cast Combat Celebrant by paying 2.
2. Combat Celebrant enters the battlefield, triggering Bramble Sovereign, causing you to pay 1 to create a token copy of Combat Celebrant.
3. Proceed to your combat phase, and declare Ghired and Combat Celebrant as attackers.
4. Ghired triggers, creating a copy of the Combat Celebrant token.
5. Exert Combat Celebrant, untapping all other creatures you control and gaining an additional combat phase after this one.
6. Repeat from step 4.
