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

Glissa, the Traitor

Krark-Clan Ironworks

Acorn Catapult

Teysa Karlov

Mana Crypt

How it works

1. Activate Mana Crypt by tapping it, adding CC.
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 Crypt 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 Crypt from your graveyard to your hand.
6. Cast Acorn Catapult and Mana Crypt by paying 4.
7. Repeat.
