I'd say this team is slightly walled by AUGUSTBOT.
Haha, this team is great. I saw it in action against BK.
Depending on Rotom-H to stop Lucario is never good. Scarfed Rotom is extremely easy to Pursuit, resulting in a Lucario weakness. Since Lucario can set up on CB BP and Pursuit from Scizor, Dragon Claw from Flygon and more, he can threaten your whole team with a +2 Extremespeed.
So, I suggest switching one of your pokemon (maybe Rotom?) to something that can take on both Lucario and Tyranitar with ease, while keeping up the offensive pressure. I think I have a solution: ScarfRachi:
Jirachi @ Choice Scarf | Serene Grace
Jolly Nature | 6 HP / 252 Atk / 252 Spe
Iron Head / Fire Punch / Thunderpunch / (U-Turn / Ice Punch / Trick)
Jirachi can check DD Tar and SD Lucario (if it has enough health to survive a +2 Extremespeed), while also covering Adamant Salamence (Ice Punch is preffered, but since you have Scizor, Ice Punch for Mence is less needed) and Jolly Gyarados. U-turn can keep up the momentum while Trick can be an "oh shit" button when things get out of hand.
If you find a place for this guy, it can help you greatly against your problems, but it'll probably ruin your team a bit (as with all good team). The choice is up to you.
