Gaaah I'm stuck!!!

Yeah, well, I recently began playing, and I have never played this game, only XD, and I'm kinda stuck. I'm in the town The Under, and I battled those two chicks from Cipher (who were pancakes compared to my awesome duo) and the guy they have prisoner is still in that cage. I have no clue what to do and I need some help. I've seen the cutscence with Ein and everything, and I can't go into the colosseum because the chick at the counter says that Lady Venus has to give out the prizes and blah blah blah.

So far I've been purifying my Pokemon. A little help, please?

Oooh, that cutscene with Venus and Ein... Hmmhmm.

If you talk to Silva in his cage, he'll give you the R-Disk so you can get to Venus's building. She'll be doing a TV broadcast, and if you talk to her, she'll come at you with her Shadow Suicune. She's hard, so train before you attack her. You have to beat her to get further.

VenusxEin... VenusxEin...

LOL. It's not a problem now. I posted that before my memory card went whacko and made me restart my game. I'm trying to beat Evice. The idiot let me snag his Tyranitar and then I got whooped. Haha, that's too bad for him.

Thanks though. ^^

he will just use slaking which is lv. 60 and harder to beat

Hmm.. Tyranitar is like the strongest to catch, right? Well if you still have the master **** use this trick
