A Banning System where you can ban out certain ninjas that your opponant cant play for that series.Before you actually pick your ninjas, there would be a time period where the players get to ban ninjas for that first match. For the following matches the ban system would take place also.

I had this idea when playing LoL, having a banning system would seem interesting and would bring more variety for space time matches.
It would force players to come up with different and unique lineups, all these immortal and blitz teams could be switched up with a banning system.

Bringing variety would be nice in these Space Time matches.
