>>21463463Battle Factory uses rental pokemon that get better as you build up a win streak. Each time you win you can swap one pokemon from your team for one from your opponent's
Battle Dome was literally PWT Lite
Battle Tower is just like Maison and the Battle Subway, but in a tower
Battle Pyramid puts you in a dark pyramid with the goal of getting up to the top, seven floors iirc. There are wild pokemon and items are allowed in battle, but only items that you find in the pyramid. Each run has a theme, like fighting lots of fire/poison/electric pokemon that inflict their respective status conditions
Battle Arena judged your battling style instead of just your battling skill and you could win without fainting all of your opponent's mons
The Battle Pike is fun, and probably one of the easiest of the frontier challenges. Battle Palace takes a lot of luck because you don't control your pokemon at all, they choose moves on their own based on their nature and remaining HP
