Yes, I know that your suppose to beat the region before you can bring your old pokemon into that certain region.   
But my idea is That when we beat a gym we can bring a certain level of pokemon.   
No Gym: 1 - 10 
Gym 1:   11-20 
Gym 2:   21 - 30 
Gym 3:   31 - 40 
Gym 4:   41 - 50 
Gym 5:   51 - 60 
Gym 6:   61 - 70 
Gym 7:   71 - 80 
Gym 8:    Any   
 :thanks: for reading my idea.  :Angel:
