Zethi, Arcane Blademaster + Final Fortune + Platinum Angel

Zethi, Arcane Blademaster

Final Fortune

Platinum Angel

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, however you cannot lose the game due to Platinum Angel.
5. Repeat each turn.
