This is quite an interesting team however I feel like it could be improved. Kingdra seems to be your main sweeper. While Choice Specs Kingdra is a pretty strong set (it's actually my favourite Kingdra to use and I use it a lot), it's not very well suited as a late game sweeper. You should perhaps try out a different set. The Life Orb version with Rain Dance is much more suited to sweep the opponent late game than your current set. Offensive teams are litteraly destroyed by its Speed and coverage, and Kingdra is quite bulky with very few exploitable weaknesses making it a tough foe to take down. It also won't be locked into one move like the Choice Specs version, since being locked into Hydro Pump really sucks when you could just take down the enemy Dragon type that tanks your Water STAB, as Rain won't last forever. Tornadus-T might be reliable at setting up Rain Dance but, Kingdra can also do it itself pretty well as it doesn't need a lot of moves to have good coverage, and having two Rain Dancers might really help your team being less predictable (i.e. having to go to Tornadus-T every time you want Rain).
Try out Superpower on Tornadus-T instead of Focus Blast, with a Naive nature. The main reason for this is that, some Tyranitar will be able to survive Focus Blast (the Specially Defensive version) or Focus Blast will just miss, leading you to getting Stone Edged to death. Superpower is a clean OHKO on most Tyranitar except really weird physically defensive versions or Chople Berry versions, but that's kinda rare. Tyranitar will switch into Tornadus-T often when it sees it use Rain Dance so taking it down will be very important in order to win the weather war. Tyranitar will be the most common weather inducer that you want to take down anyway, and one of the few things you really need your Fighting coverage for, the other being Heatran who takes a load from Superpower anyway.
I get that Taunt Skarmory is great, but honestly I don't think that you need it on your team since you have Gliscor. Gliscor is already pretty good at stopping most Spikers/SRers for setting up their hazards anyway, especially Skarmory. Brave Bird is really a great move for Skarm as dealing with Breloom is incredible, along with being able to nail Flying weak Pokemon on the switch. You might want to use a different spread on Gliscor with that moveset though. Try using 216 Speed EVs with a Jolly nature, as it allows you to outspeed Deoxys-D, one of the most common offensive leads, and you will still be able to Taunt pretty much anything that sets up on you anyway. It also stops the very random Jolly Ice Punch Lucario, which is fine I guess.
So yeah, nice team, here's the set you should use:
different Kingdra set!
