As shown in the synergy chart, this team has a huge weakness to Water-type moves. In particular, Life Orb Starmie can easily 2HKO every member, allowing it to make a clean sweep after a bit of residual damage. Infernape is also a major threat; although you list Gyarados as an Infernape counter, it simply does not serve that purpose well. A large number of Infernapes run either Stone Edge or Thunderpunch, meaning even Gyarados is going to be taking huge damage.
To help you take Water attacks and retain the ability to stop Gyarados, try out a Celebi in place of Rotom:
Celebi @ Leftovers
Ability: Natural Cure
EVs: 252 HP/224 SAtk/32 Spd
Modest nature (+SAtk, -Atk)
- Grass Knot
- Thunder Wave
- Hidden Power [Fire]
I prefer this set because of the extra power and ability to OHKO Scizor after Stealth Rock with Hidden Power, but the standard Defensive set is also an option.
Speaking of Stealth Rock, you don't have a user of it on this team! You absolutely have to have a team member to set up Stealth Rock on any competitive team, as the entry damage is invaluable.
I would recommend switching out the Anti-Lead Gallade. I know that you're satisfied with its performance, but it can't set up Stealth Rock and a Choice Scarfed Pokemon like Heatran isn't a good option to carry it either. Try out a TrickScarf Uxie in its place:
Uxie @ Choice Scarf
EVs: 252 HP/104 Def/152 Spd
Impish nature (+Def, -SpA)
- Thunder Wave
- Stealth Rock
Uxie matches up better against more leads than Gallade. It's somewhat of an anti-lead and a Stealth Rocker all in one. Against both faster leads with Taunt, and slower, bulkier leads, Trick will most likely end up crippling your opponent. Thunder Wave can then be used on the switch to paralyze anything that comes in, while U-Turn gives you a more fluid way to switch.
Good luck with your team!
