Ghyrson Starn, Kelermorph

Gisela, Blade of Goldnight

Switcheroo

Cadric, Soul Kindler

How it works

1. Cast Switcheroo by paying its mana cost, giving control of Gisela to an opponent.
2. Cast Ghyrson Starn by paying 1.
3. When Ghyrson Starn enters the battlefield, Cadric triggers, causing you to pay 1 to create a token copy of Ghyrson Starn with haste.
4. Deal exactly two or three damage to the opponent, which is reduced to one by Gisela, triggering Ghyrson Starn and the Ghyrson Starn token.
5. Resolve the nontoken Ghyrson Starn's trigger, dealing 1 damage to the opponent.
6. The token Ghyrson Starn triggers, dealing 1 damage to the opponent.
7. The nontoken Ghyrson Starn triggers, dealing 1 damage to the opponent.
8. Repeat from step 6.
