O-Okay, mod-kun. .__.,
>>13605082>BreloomSleep fodder something, then take it out with Latios or Gengar. Even Weavile revenge kills it if need be. Alternatively don't let it come in and get Spore of in the first place. Your setup really shouldn't have any problems with Breloom if played correctly.
>GengarReplacing Gengar is fine. Jellicent however doesn't look like a good fit for your team. You'd be much better off with a generic physical walls like Landorus-T or Skarmory.
As far as Weavile is concerned, SD sets really don't work in OU at a moderately high level. I can only urge you to use a Pursuit trapping set instead and play to its strengths or replace Weavile completely.
>>13605096Looks rather solid to be honest.
I'd definitely run Leftovers over Air Balloon on Ninetales though. Also your team really wants Stealth Rock. You could just splash it on Nyandorus, since Gravity... well, kinda sucks. It does help Landorus to take down Skarmory, but your team actually shouldn't mind Skarmory at all. In fact you can just use it as setup fodder for Forretress.. It should also be noted that you don't run many moves with imperfect accuracy, so Gravity might actually help your opponent more than yourself. Oh, it also grounds Cress, which kinda sucks.
