Lich's Mastery + Isochron Scepter + Final Fortune

Lich's Mastery

Isochron Scepter

Final Fortune

How it works

1. Activate Isochron Scepter by paying 2, casting a copy of Final Fortune without paying its mana cost.
2. Resolve Final Fortune, taking an extra turn after this one.
3. Repeat each turn.
4. At the beginning of each extra turn's end step, Final Fortune triggers to cause you to lose the game, but you cannot lose the game due to Lich's Mastery.
