I can actually see them doing a victor battle gauntlet for their 9th.
Imagen Lucina, Camilla, Ike, Hector and Lyn in 1 voting gauntlet.
Anyway, I'd change the point system to a similair point system of the arena.
The more characters survive, the more points you get.
For example you get 100 points as basis
+10 for using the hero you vote for
-20 for every hero in your control that gets killed.
So it doesn't become a pointless autobattle fight.
