Training high level pokemon

This is for black 2. My problem is that once my pokemon get to about level 80 it takes forever to train up to 100. Is there a faster less painful way to get these last 20 levels?
I understand if you don't want to give out your training strategy but thanks anyway

The only thing i do is trade to my white 2 or black and white and train the pokemon with a lucky egg, best way i know

OR we can do this. I give you my fully EV trained pokemon and you level them to 100 and I level your EV trained pokemon to 100. That way we both get what we wanted and then at 100 send them back to each other Traded pokemon level Twice as fast. (and I have 3 lucky eggs :X)

Sounds like a plan bba. I just have to get my wifi working which is hopefully soon

Great. Can't wait. I'm suffering trying to raise this Dragonite since it refuses to breed with the hidden ability . Already breed about 4 of them but the % is low to breed one with its Dream World ability. So I need a fast way to level it. Have you gotten a lucky egg yet?

yeah i have one. Just got my wifi working so i'm cheering.
I can try raise it for you. Can we do a trade sunday maybe?

Sure. Sounds great. What pokemon do you want me to raise for you?
