It's an outdated team, especially have hypnosis got fucked in the Platinum change.
Gengar (hypnosis, WW, focus blast, shadow ball)
Zapdos (agility, baton pass, charge beam, roost)
Empoleon (SR, grass knot, Ice beam, surf)
Kingdra (rain dance, surf, toxic, HP elec)
Machamp (rest, dynamic punch, stone edge, sleep talk)
Metagross (EQ, explosion, MM, TP)
I haven't played in months (and that was only was a week... I haven't played in more than a year for a 'real' streak), but the team fared quite well against the current metagame, though I was screwed at first when I saw new rotom forms and was like 'wtf are these'.
