Ah, Gen 3. My favourite generation! This should be interesting.
Earthquake>Fly on Salamence to deal with Ice-types. Take out Dragon Dance, and put in Double Edge.
Swords Dance on Blaziken, and instead of Flamethrower, give it Overheat, or Fire Blast. Take Brick Break out, and put Rock Slide in.
On Gengar, take Giga Drain out, and put in Shadow Ball.
I'm not sure why you gave Ludicolo an ability that needs rain for it to work, when your team has no means of getting rain. I'd use Cloyster instead, with this standard set:
Cloyster @ Leftovers
EVs: 252 HP / 16 Def / 88 SpA / 148 SpD / 4 Spe
Bold Nature
- Spikes
- Rapid Spin
- Surf
- Explosion
That's all, I think - good luck!
