You're making no use of Ninetales Drought; this isn't a sun team. I'm not giving a set for Ninetales because this team makes no use of Sun whatsoever.
Espeon @ Leftovers
Trait: Magic Bounce why would you use synchronise when Magic Bounce reverts the opponent's status move back onto the opponent?
EVs: 252 Sp. Atk, 252 Speed, 4 HP
- Calm Mind
- Hidden Power Fighting
- Reflect/ Morning Sun
Scizor @ Choice Band
Trait: Technician this is the superior ability for Scizor and the main reason why it's OU
EVs: 252 Atk, 252 Speed, 4 HP
- Bug Bite
- Bullet Punch
Breloom @ Toxic Orb
Trait: Toxic Heal the Toxic Orb will replenish 12% HP every turn, as opposed to Leftovers 6%. Also, it will prevent your opponent from giving you a status move
EVs: 252 Atk / 252 Spd / 4 Def
- Focus Punch
- Bullet Seed (this will break substitutes and do damage to the opponent)
Dragonite @ Lum Berry
EVs: 252 Atk / 252 Spd / 4 HP
- Dragon Dance
Blissey @ Leftovers
Trait: Natural Cure
EVs: 252 Def / 4 HP / 252 Sp. Def make full use of Blissey's special defence by investing max EVs into it
- Seismic Toss/ Ice Beam
I saw your other thread on this team; if you want to use Ninetales, make a team that will actually benefit from Drought (e.g. Venusaur with Cholorphyll). Otherwise, use Heatran like the other thread suggested.
There is no need for Block on a Blissey. Give it Aromatherapy which will give you team support (though it will inadvertently heal Breloom).
