Battle othe people or leave them in the day care. However, you can't choose what moves they will forget or learn and they won't evolve.
Anything you want but they get higher levels each time
It could change Stat levels (higher)
higher than his
You can have up to level 100.
Make sure your Pokemon are a few levels higher than the Gym Leader's Pokemon.
level your Pokemon to high levels such as: lv.12,15,29 or higher. But if you give them an everstone you can't evolve your Pokemon.
The more steps you take the higher exp it will learn.
Yes, you can. I have no code, but try a Google search.
There are levels from 5 to 80, and they are really strong.
its probably going to be a pikachu, voltorb, and a raichu at levels 24 or higher. for sure raichu might be lvl 27
I think you should have a ghost Pokemon that is 3 lvls higher than Fantina's and have a Physic Pokemon like alakazam.
Ok, I am just ashamed that someone would ask this question. Train in tall grass, catch legendaries, and make sure your Pokemon are all 3 levels or kore higher than the gym leaders' toughest, and 5 or more levels higher than the champion's toughest. It's the same for every Pokemon game.
