Help me with my new VGC team?

As Black said, your team is weak against Sylveon's/M-Gardevoirs hypervoice. Actually 3 members of your team will be KO-ed by it. (+ Raichu will survive with 1 HP or so)
I know you run Heatran and Bisharp to stop the fairy spam the only problem is that Mega-kang is still a thing. I saw it a lot and it's still number 1 most used pokemon in the meta so far.

I've battled a lot of people on showdown and most Sylveon-teams also have a Mega-kang with them, and she can actually take out your Bisharp in one hit and Heatran in two/three hits (I didn't calc the fake-out damage with this) so I should try to find a counter to her since I can see that Kang's double-edge can become a real problem for your team if you don't have a good counter for it. Like you could use a weakness Policy physical Aegislash as a example since Kang can't hit him with a double-edge and it can survive a Sucker Punch from her. + Aegislash can learn wide guard so you can stop the hypervoices and your weakness to earthquakes with this :D

Some calc stuff for a standard physical Aegislash (In shield form)

252 Atk Parental Bond Kangaskhan-Mega Sucker Punch vs. 248 HP / 0 Def Aegislash: 96-114 (57.8 - 68.6%)
*Weakness Policy steps in*
+2 252+ Atk Aegislash Sacred Sword vs. 4 HP / 0 Def Kangaskhan-Mega: 250-296 (138.1 - 163.5%)

Without the boost
252+ Atk Aegislash Sacred Sword vs. 4 HP / 0 Def Kangaskhan-Mega: 126-150 (69.6 - 82.8%)

Also lol I just saw that Black was warning you about a wide guard Aegislash before
