yes
beat alot of trainers
You can cath alot of Pokemon That helps... But really, there are many of them. all of them can be caught. except other trainers. but with a gameshark, you can catch all Pokemon you meet. but other trainers' Pokemon become bad eggs.
You can't steal Pokemon however in Pokemon colosseum and Pokemon xd gale of darkness you can snag shadow Pokemon from trainers.
to get data on Pokemon in your pokedex, capture the Pokemon unless they are trainers Pokemon then you have to cheat to get trainers Pokemon.
No trainers will have articuno.
beat the elite 4, become champ.
Pokemon and pokeballs
Try looking for water trainers and fisherman, or else evolve a feebas by maxing its beauty to become Milotic
Well, by 'Trainer' I'm guessing a Pokemon Trainer. Well, not sure if this is the official way but, here we go: When you're eleven years old, you can become an official Pokemon Trainer. To start off, you have to get an starter Pokemon by an professor. Afterwards, with your Pokemon you'll battle against other Pokemon Trainers and if one faints, you'll get experience. Along the way you will meet your rivals, other Pokemon Trainers along as battling Gym Leaders, a special type of Pokemon Trainer and after you get all eight badges, you'll versus the Elite Four, the most strongest Pokemon Trainers of all time. So uh, yeah.
No
you need two batteries double a batteries at the side of your game boy colour then trow a pokemon ball at the trainers pokemon
trainers don't hold them get a Pokemon that has the ability pick up like meowth or zigagooon
