Fun little thought experiment I and a handful of friends came up with

There are three main X-Men characters who have some sort of probability manipulation/ luck/ cant-lose powers. Domino, Longshot, Isca the Unbeaten. Each with some drawback, Longshot must be selfless, Isca often switches sides, etc

Assuming a perfect scenario where Longshot is fighting for a selfless cause and Isca cant change sides, who would win if they all decided to fight?
