Glissa, the Traitor + Krark-Clan Ironworks + Acorn Catapult + Teysa Karlov + Mana Vault

Glissa, the Traitor

Krark-Clan Ironworks

Acorn Catapult

Teysa Karlov

Mana Vault

How it works

1. Activate Mana Vault by tapping it, adding CCC.
2. Activate Acorn Catapult by paying 1 and tapping it, targeting a creature an opponent controls with toughness equal to one.
3. Holding priority, activate Krark-Clan Ironworks twice by sacrificing Mana Vault and Acorn Catapult, adding CCCC.
4. Resolve the Acorn Catapult ability, dealing 1 damage to the creature, causing it to die due to having zero toughness, and causing its controller to create a 1/1 Squirrel creature token.
5. When the opponent's creature dies, Glissa triggers twice, returning Acorn Catapult and Mana Vault from your graveyard to your hand.
6. Cast Acorn Catapult and Mana Vault by paying 5.
7. Repeat.
