please tell me you can do maths.
Tangerine is missing 2 EVs!
This team is very similar to one of my teams for which the defensive core is Reflect Cresselia, Roaring Swampert and Sleep Talk Zapdos.
That team's main problems occur when Swampert goes down, at which point Tyranitar tends to become a huge problem (however, with Lucario and Scizor you shouldn't have any problems with it...). Additionally it cannot beat Toxic stalling Zapdos when it is accompanied by something that beats my own Zapdos. Gengar can also be troublesome, but you appear to have found the answer!
Since you don't have Psychic Cresselia, I suppose you will also have trouble with Infernape and Breloom which I happened to have trouble with before I made that edit to my team.
Porygon2 looks like the best candidate for replacement, since it is just providing a redundant BoltBeam and attempting to counter what Cresselia would be countering anyway. Whether you keep a similar set replacing Thunderbolt with Psychic is up to you, but it would help to beat the aforementioned Fight types.
This would open up a Dark weakness but you have Scizor and Lucario already so hopefully that won't pose too much of a problem. Swampert + Cresselia + Zapdos are quite a good defensive core in my opinion (despite Swampert/Cresselia's lack of good recovery

), especially when accompanied by a good Dark resist.
Toxic stalling Zapdos isn't very common but in the event that you see one I would suggest setting up Light Screen then scaring it away with one of your sweepers... Hopefully you won't come across one at all though
To be honest, this team looks like a combination of two of my best teams + a Scizor, which is pretty cool
P.S. Nice format!
edit: MoP's support Salamence suggestion may also be a good idea, although it would probably make you even more Zapdos weak unless you used a RestTalk Cresselia/Heatran instead (Cresselia might not beat Zapdos assuming Zapdos switches when its SDef falls but Zapdos won't beat Cresselia either!)
