Gideon of the Trials + Isochron Scepter + Final Fortune

Gideon of the Trials

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 Gideon of the Trials's emblem.

By utilizing Isochron Scepter to repeatedly cast Final Fortune, you chain extra turns indefinitely without ever giving your opponents an opening to act. The true genius of this loop lies in Gideon of the Trials, whose ultimate emblem ensures that you simply cannot lose the game. Even though Final Fortune's delayed trigger attempts to make you lose the game at the beginning of each extra turn's end step, Gideon's emblem shields you from defeat, allowing you to safely repeat the process forever.
