In Pokémon Colosseum's Mt. Battle 100 Knockout Challenge, the highest-level Pokémon that trainers use is level 50. The challenge consists of battling through a series of trainers, each utilizing a variety of Pokémon, but all are capped at this level for balance. This allows players to strategize and adapt their teams to face different opponents without exceeding the level limit.

you need to battle a trainer with shadow Pokemon, you will be able to "snag" it. it will only have one move and will not be able to level up until you have purified it. it will then learn moves. this is the only way to catch Pokemon in Pokemon colosseum.

Yea
Deep Colosseum for Story Mode. This is where you'll have to battle in the 5 rounds to pick up a Shadow Pokemon named Shuckle. After that Togetic will be available to you by a Cipher Peon impersonating you. If you're in the Battle Mode, it's either Orre Colosseum or Realgam Tower but I haven't played much in the Battle Mode in a long time because I don't like their level restrictions and for the Story Mode, we have to train way higher if we want to succeed.
You need to have gotten the mystic ticket from the Nintendo event but it is already over so the only way to get a ho-oh now is to get one from Pokemon colosseum which you get by training your Pokemon in colosseum to the same level such as 70 then use your story mode pack in the mt battle vs 100 colosseum battle you don't need to win consecutively but you can't lose your continues.
only one he asks you what level he should take in the challenge
Don't need one cause you can trade a ho-oh from Pokemon colosseum. Beat mt battle vs 100 with your story mode pack in colosseum to get a free level 70 ho-oh.
