Battle other trainers until you are strong enough to beat the elete four then mop the floor with them over and over again.
You could add a garachomp, salamence, and deoxys to make your team better.
Get all u can and try to save them and then if u get a better Pokemon can select it and make it leave
no not realy you better choose you own team

You can not make a team. I have it and i played it like 5 times already and I can not make a team. The only way is to forget about it and buy another pokemon game. This one is bad.
You train them
Roserade but it depends on your team...
to say Pokemon red
both of course!
This is a pretty balanced team, but try to get a better grass-type Pokemon to balance it out.
It's hard to say who's better, since it depends on a number of factors, including the moveset, what other Pokemon are on your team, and the Pokemon's nature.
Battle and level up
