Composite X-Men team, as in a composite Xavier, and a composite Wolverine etc. using up to ten X-Men vs a composite Superman. Anyone who has been a member of the X-men can be used. Stacked or unstacked, but if you stack the X-Men team you must stack Superman. If you give prep to one side the other gets equal prep. If its a stomp either add more members to the X-Men team OR Superman can add team mates from the Justice League (not sure what way it will go!).
