How do you make your Pokemon invincible?

Answer 1

Well you could either train and train and train and train until you reach level 70 or higher for all of your Pokemon or you could buy a ds action replay at most wal-marts or targets. But ds action replays are kinda risky and can cause the game to have multiple problems, like freezing up in the middle of battles.

PS. Ds action replays don't cost that much mabye 20 dollars at the most, and work for many more games besides that one.
