Why would run the completely useless Hyper Cutter on AcroBat when you could run Poison Heal so that you can use Gliscor for status fodder and get recovery.
btw, the magic Poison Heal numbers are divisible by 8 + 1, so Chimpakt is right about 244 HP EVs for the defensive set and SD at least. You're best off with 248 for Substitute sets. I'll do some math to make sure there isn't a more optimal spread for Defense.
