If the Villains of "Friendship is Magic" were to engage in a free-for-all battle, which of them would be the last one standing?

[Jerry246 37]

Specifically unreformed villains. Chrysalis, King Sombra, Cozy Glow, Storm King and Tirek.

The context here being that they formed a legion of doom sans Grogar. without him to keep them in check and once they achieve their shared goal of conquering and destroying Equestria as well as the rest of the planet, the legions falls apart as conflicts of interest,selfishness and greed set in and the Villains backstab one another. Sharing power was never part of their agendas as seen in the show and in The Cutie Remark. So when they start murdering each other in this scenario, what villain would emerge victorious from this deathmatch and be the last one standing?
