Well, this team can use a little improvements:
Typhlosion - Flamethrower is great, since he has way better sp.attack than attack, you should switch flame wheel and blast burn (USELESS!) to solarbeam-sunny day combo.
Empoleon - Teach it Ice Beam, Surf, Flash Canon and Grass Knot for great moves.
Torterra - Earthquake, Seed Bomb, Crunch and Stone Edge.
Mew - First - how the hell did you got one? Oh well, just give it a simple Flamethrower - Ice Beam - Calm Mind - Psychic moveset and you are good to go.
Yanmega - A decent moveset would be
Ancient power - Bug Buzz - Air Slash - Giga Drain
Dragonair - As it evolves, teach it
Stone Edge - Dragon Claw - Fire Punch - Brick Break
Thats what I think about it so you can change it a little but thats the overall direction of movesets.
