HP water is probably the best choice for an attack on blissey.
It can break gengar's subs (just like ice beam), Seriously screw up dugtrio, break T-Tar subs ( Ice beam can't), and it helps counter other random stuff.
Taunt on Skarmory is a complete beast. It stops almost everything that will piss skarm off.
BTW I took rest off for steel wing
Quick attack is for Endure/ Reversalers
