Holy crap, we both have stall RMTs with Ditto and Crocune, two very unusual pokemon!

Your team can kind of die to some well placed toxics or other status, but mainly toxic. You say Dusclops's only purpose is to stop Aegislash, but you have Entei, Suicune, and Ditto in a pinch. Honestly, you need to swap Dusclops for a good cleric. Blissey, Chansey, Sylveon, or Umbreon could all work. Also, I'm seeing Entei have low survivability with rocks, and Zapdos isn't a big fan either. Mandibuzz could also be a potential Dusclops switch because the best Aegislash can do to it is an iron head/flash cannon which is probably slower than the incoming knock off or foul play. Finally, the idea of your team seems to be extreme bulk with good survivability that doesn't waste time. For me, I would go to Slowbro or Cresselia. Two water types with Slowbro and Suicune isn't too problematic when you consider the types that they're weak too, and both can ice beam strong dragons that are only stopped by Ditto. But if you want more effective ratings, I suggest that you put in your own threat list. It could help (not that my RMT is successful in any way, shape, or form).
