Ghyrson Starn, Kelermorph

Gisela, Blade of Goldnight

Wrong Turn

Irenicus's Vile Duplication

How it works

1. Cast Wrong Turn by paying its mana cost, giving control of Gisela to an opponent.
2. Cast Irenicus's Vile Duplication by paying its mana cost, creating a token copy of Ghyrson Starn that isn't legendary.
3. Deal exactly two or three damage to the opponent, which is reduced to one by Gisela, triggering Ghyrson Starn and the Ghyrson Starn token.
4. Resolve the nontoken Ghyrson Starn's trigger, dealing 1 damage to the opponent.
5. The token Ghyrson Starn triggers, dealing 1 damage to the opponent.
6. The nontoken Ghyrson Starn triggers, dealing 1 damage to the opponent.
7. Repeat from step 5.
