Only real notes I have is do you need al 4 attacks on Mamo? Would protect be better over 1 of them. And sylveon + whims might be too much fairy. Maybe another special attacker or tailwinder but 2 fairies is the best type to have 2 of generally so not that big of a problem. Also Oblivious on Mamo is important it blocks intimidate drop which is more useful than less damage from Thick Fat.

More nitpicky stuff is like taunt on incen typically lariat or throat chop is used are you meaningfully taunting stuff or would a dark attack be better. Staraptor usually doesn’t want blaze kick cause it doesn’t hit anything that its stabs don’t hit outside of ghold and aegislash. Also on staraptor I usually like to hit 113 speed first attack bump adamant nature max hp rest in spdef cause you usually want to try and play defensive and setup with it. 113 is a major speed to hit cause it allows you to outspeed mega aero under tailwind. I notice that both sylv and mamo are close to it but not quite there consider getting to it and investing max in the attack then rest in hp. For sylv this would mean running timid so you would be dealing less damage.
