Hammer Arm and Agility are a bit pointless; seeing Hammer Arm decreases your speed everytime you use it. I would advise keeping only one, I would think to keep Agility and put Earthquake, so you can beat Steels that can wall that set with relative ease.
Good point on the Hammer Arm, although if I switch it with Earthquake then I risk having too many Earthquakes 
.Definately give Scizor a Bug STAB over Pursuit, like Bug Bite, as Pursuit is generally only for revenge killing, not for a setup sweeper.
I need a pokemon with Pursuit, as it will greatly help in the opponents I'm versing. Should I add it to Tyranitar perhaps? Also, what Bug Stab move? I can easily give it X-Scissor, but that's not taking full use of Technician and I'd rather see Pursuit being boosted.Give Latias Surf over Psychic, so you don't get destroyed by the likes of Scizor/T-tar. I'm not sure about Charm, I don't think it is even allowed so maybe change it.
Surf is a good option, and has been recommended by Smogon. I would give it Surf, but I already have a Suicune and thus it would make it kind of pointless to have Surf on both... I also have no Psychic moves other than this. I'm thinking teamwise here, not individually. Still think I should drop it?Fire Punch over Fire Fang, it has both more damage and more accuracy.
Definitely. But how? I don't think it can be tutored... Not sure about T-Punch on Dragonite, Fire Punch or EQ would allow you to hit Steels harder, which are the only type to resist Dragon.
This is what I definitely wondered about here, but opted for Thunderpunch because at the time I lacked lightning moves. Now with Zapdos it seems kind of pointless, and will probably exchange it for fire punch. Thanks for pointing it out!Aero/Suicune seem fine
And yes, I think you have too many sweepers and not enough walls, you have 3/4 (if you count suicune) setup sweepers; which is an awful lot for one team
Maybe keep 1-2 you would like to use; then work around those 2 in particular
