battle facility that randomly swaps your team with the opponent's - they could end up getting a team full of fully EV'd monsters or baby pokemon shitmons.
battle facility that is a speed competition - you must fight a number of opponents with other contestants. the one who beats all opponents in the shortest number of turns wins.
not really a new facility, but a contest where your pokemon actually duke it out with others using your contest moves and trying to gain appeal from the judge while fighting.
a facility where you are allowed to use only one banned pokemon - groudon, kyogre, etc. the catch is your opponents can use one banned pokemon too. this would include everything from mega fug to phione.
a facility that lowers or heightens your pokemon's stats to be 100 all across the board (like mew, manaphy, etc). maybe could be a mode on battle tower too.
a facility that forces you to play under a certain condition for a whole battle - electric terrain, misty terrain, rain, harsh sun, etc.
