keep two pokemon in the daycare. go to the sandstorm and try to cycle up the sand slide. use something heavy to press on your up directional button. after few hours your pokemon will up tremendous levels. because when you go up its considered one step and slide down another step. just by pressing up 1 times at the sand slide is equal to 2 step when you are walking

cheat
try rare candies
Pokemon day care or put exp.share on a weak Pokemon
To get a Pokemon level up quickly is to have a Pokemon hold exp. Share and then just battle a bunch of trainers or wild Pokemon.
either cheat or battle the as many trainers as possible
keep battling Pokemon and people
Defeating Pokemon that are a higher level that it, or Rare Candies.
Dark Cry? There is no such game. I belive you mean how to level up the Pokemon DARKRAI. Correct?
If you have the Exp.share give it to your Pokemon that you want to level up then go to beat the elite four and the campion
By giving it rare candies :)
I think Gardevoir is a good Pokemon who learns Hypnosis at level 51
