I suggest challenging the elite four over and over again. You gain the a lot of experience in a short amount of time. Also use the Vs. Seeker on trainers you have previously battled that gave you a lot of experience such as trainers on the islands that are open to only trainers that have beat the elite four.
Action Replay.
with action replay or luck
Action replay
well, you can't really clone them without a AR
No
no you have to get is from an action replay or go to a Pokemon event
I'm sorry but you cant capture a trainer's Pokemon without an action replay.
you trade it or use action replay
only with action replay!!! there is no way without action replay
you have to migrate or use action replay
No you can not.
you do not need to buy action replay. its just really hard. battle a lot and you may find one. bring a quick ball on your journey!
