After another year of Batman getting coal in his stocking for being a jerk and Santa eating all of Martian Manhunters cookies, the JLA has decided Santa must be stopped! The JLA then launches an attack on the North Pole.
Assuming a composite Santa and his helpers (elves, reindeer, snowmen, Ernest P. Worrell. etc) how does the Justice League do?
How many non-active, and backup members do they need to call it to make it a decent fight?
