Uh, Your rate was for like an RS team :p
Venasaur@Miricle seed/Leftovers
Giga Drain or Earthqake or Sludge Bomb
Sunny Day
Solarbeam
Synthesis
In GSC, Starting with Venusaur has but 1 course of action: Sleep powder. It doesn't get Quake/SBomb in GSC anyways, so it's more or less not as offensive. Fire moves are still quite popular, so I'm not sure if you'd really want that set to begin with, but to each his own. Personally though I'd use Venu for sleep powder and util moves like Leech seed and Body slam (so you can inflict SLP and follow up with PARs and such to force switches?)
Dragonite leftovers
Thrash
Thunder Wave
Thunder Bolt
Stregnth???(I want to make good use of its high attack) maybe fly no ahh need help here posssibly slam??
Twave is good in GSC, it causes PAR, which is nice. Thrash and Strength lack the power or usability, so ditch them. One of the Dragonites you can consider is a hazer, which is always nice, but you'd need some staying power for that really. Alternatively, go for HP fighting, Wing attack, Twave and Flamethrower/Tbolt as a sweeper type, but more or less watch out how you use up your health due to no recovery.
Gengar:
Shadow Ball
Physcic
??????, maybe HP Ghost, Pioson, maybe HP dark
??????
Gengar's attack is so bad in GSC era that its only usable physical attack is Explosion, so consider that. Either way, have Destiny bond or Explosion handy (not both) so if you are near dead you can use them. Item wise, Miracleberry is your best bet, if not PRZcure is nice too. Attack wise, you have 3 slots to play with, so you can always go confuse ray and 2 specials, or just go 3 specials, no one really minds either way =) (Ptrap with gengar isn't as effective as say Jynx or Misdreavus)
Scizor
Slash
Swords Dance
Agility
Fury Cutter
Scizor's really usable for 2 things: BP or Reversal, since it'd do more damage than regular sweeping. Either way, keep Agility. If BP, stick Baton pass over Cutter, and have HP Bug over slash (OR steel wing). If Reversal, stick Endure and Reversal over Slash and Cutter, but you may choose to keep HP bug over SD if you think it'd work better that way.
Kingdra
Surf
Thrash????
Twister???, maybe HP Dragon insead
Hp Ice or Ice Beam
Kingdra's more annoying than offensive, or defensive for that matter. Go with the age old standard Dbreath/Surf/Rest/Sleep talk, or you can have fun with like Smokescreen or curse or whatever =) Thrash is a bad attack, and HP is a bad idea since you'd usually have to lower a LOT of HP and stuff just to make use of HP.
Forrtress
Spikes
Rapid Spin or Explosion for a kamicazi if nessacary?
Earthquake
Toxic??/ maybe something like counter
Forretress can't get Counter and Earthquake, iirc. Rapid spin is nice for util, but if you go Explosion, ditch Spin. if not, then have rest over Quake, and have like HP bug or something as your attack move? Or toxic, or Reflect, or whatnot.
Overall: Lacks physical force in general, no Rest bell may be a breath of fresh air in GSC, but it won't last as well against teams that do restbell, at least, in general that is.
