While I prefer Motor Drive, I do think Water Absorb is worth making the slate. It may not partically help CAP 6 with sweeping beyond getting more HP for Belly Drum, but the Water immunity gives it new set up opportunities vs stuff like Politoed, which is pretty invaluable! As for Magic Guard, something I do like about it is allowing us to use recoil moves for easier sweeping with Belly Drum. But like people have mentioned, Magic Guard makes Life Orb a non issue, so we could easily end up with another Krillowat situation. Also, Magic Guard doesn't help with the actual Belly Drum set up that much. I'm not totally against it getting into the slate though, because I think our experience with Krillowat could help us avoid the problems we had before. Still though, I don't think Magic Guard is that great of an option for this CAP either.
