Dragonite- Its good teach it an Ice type move to cover its weakness
Elektross- I would Suggest A water type pkmn to cover its Weakness; I would do away with Scizor.
Sceptile-Again a Water type when a fire types are in. If Flying type is your problem switch to your Elektross and Zap em'
Scizor-Like i said, Drop this.
Spiritomb-It has no weakness, good! This could be a good Stall pokemon. Moveset=Toxic, Hypnosis, Substitute, Dream Eater. It should hold Leftovers or something to improve accuracy of Hypnosis.
Blaziken-its good Keep a water and electric type to help with weaknesses. as for moveset, i prefer Physical Sweeper. it should hold Life orb. Moveset=Blaze Kick, Substitute, Sky Uppercut and A Stat raising move like Swords Dance.
Ask me about Anything else you need help on.
