Umm yes yes and yes I have no luck whatsoever.
It's easy the first two challenges (14 Battles), but then it gets real hard the third time (21 Battles). You guys should be very proud that you reach even 50 battles, I struggle to get even to 21, even with my best teams.
And my best teams have beaten alot of good battlers. Although I didn't EV or IV train...
It's kind of really hard, but it's just that when I choose my Pokemon, I'm always worrying about it. Cheats do nicely for it, but I don't recommend it.
I'd say its tough, I certainly don't win with just any random team, but if I get serious those battle points start building up. Sadly I haven't played around with this feature too much.

The Battle Tower has always driven me to the edge of supreme frustration. I always lose when it matters most, due to status conditions, or critical hits, etc.
The Battle Subway is a little bit too easy for me. I beat the Single and Super Single trains with hardly as much effort as I have had to do in the Battle Tower.
It's painfully easy. I ever use it.
Not that hard, when I lose, it's often due to my own mistake tbh.
