Zethi, Arcane Blademaster + Final Fortune + Sundial of the Infinite

Zethi, Arcane Blademaster

Final Fortune

Sundial of the Infinite

How it works

1. Declare Zethi as an attacker.
2. Zethi triggers, copying all cards you own in exile with kick counters on them and allowing you to cast the copies.
3. Cast the Final Fortune copy by paying , causing you to take an extra turn after this one and lose the game at the end of the extra turn.
4. At the beginning of each extra turn's end step, Final Fortune triggers.
5. Holding priority, activate Sundial of the Infinite by paying 1 and tapping it, causing you to end your turn and exile Final Fortune's trigger from the stack.
6. Repeat each turn.
