[SilverMaster]

i'm training up 2 new teams of 3,but i need combo advice.so far i got:

Typhlosion,lv.100
Sunny Day
Fire blast
Thunder punch
Earthquake

Misdreveaus
possible moves:
Psywave
Mean look
Pain split
Perish song
Psychic
Nightmare -involves set up from vileplume
Destiny Bond
Dream eater -involves set up from vileplume

Vileplume/bellossom
Petal Dance
Suuny Day
Moonlight
Synthesis
Sleep powder
Solar beam
- want atleast 1 healing move

,the second dilema is
Heracross:
Megahorn
Rest
Sleeptalk/snore
Counter/Reversal - this is a tough one

I also don't know how to breed synthesis into oddish without already having an oddish with synthesis, if you see what i mean.I need your helkp to tell me whats best,(stadium tournaments are their main events)

I'm not much help with most of your post, but I can tell you how to breed Synthesis onto Oddish (although Moonlight, which Oddish learns naturally, does pretty much the same thing anyway.) In Silver Version, there are three pokémon that learn Synthesis naturally and can breed with Oddish: Bulbasaur, Chikorita, and Sunkern. Sunkern is probably the easiest choice simply because you can catch them in the wild. However, if you have Crystal Version, forget Sunkern. Hoppip, which can also breed with Oddish, learns Synthesis naturally in Crystal, and it learns the move extremely early, so you don't have to raise it first.

Oh, by the way, if you're stuck using Sunkern: don't evolve it. Sunkern and Sunflora have very different move lists, and Sunflora doesn't get Synthesis.

Typhlosion looks okay. I'm not a big fan of Sunny Day, but it's usable and you already have the other off-type moves he can learn. Sunny Day would work well with Vile/Bell, as well.

Don't use Psywave on Misdreavus. Don't use Nightmare or Dream Eater. That leaves you with five remaining moves. Mean Look + Perish Song is a given. After that, you can drop any of the others. Drop Psychic if you want it to be a pure Perish Trapper, or drop one of the other two if you like to have a regular attack for back-up (consider Tbolt as well as Psychic, but not both). If you decide to be a pure Trapper, Protect is an option over Split or DBond.

Use Sleep Powder on the grass dude. Take a healing move. If you want the Grass attack on it, use Bellossom. (Sunny Day + Solarbeam works with Typhlosion, but it takes up both remaining move slots. Consider Giga Drain + _____ [anything] as well, but Petal Dance is a bad idea.) You could also use Vileplume with Swords Dance + Sludge Bomb, but stick to Bellossom if you're going to use a Grass attack.

if you insist on using Rest on Heracross, first thing: NOT SNORE! It's garbage. Sleep Talk, however, is pretty good. Reversal is an absolutely horrible move to use on a sleep-based Heracross, since you'll be wanting to Rest at low-health rather than Reversal. Counter doesn't mix with Sleep Talk. For that last slot, you can use Earthquake, or HP Rock if you have access to it. You could also use Curse, which will make you very powerful against other heavy attackers but leave you boned against anything resistant.
