I feel that an entirely physical set is in order.

Aqua Tail and Aqua Jet are STAB- one provides a strong attack, the other a priority for picking off weakened foes. Cross Chop and Shadow Claw provide perfect coverage. Ice Punch helps against Grass types, while Hypnosis shuts down walls like Politoed, and Yawn helps force switches, as well as punish switch ins.

Well, unlike Qwilfish, Golduck can provide Hypnosis or Yawn support, not to mention Aqua Jet provides it with priority, and Cloud Nine shuts down Snow Cloak other weather based abilities AND boosts. Snover can be put to sleep and later taken out with Cross Chop and Aqua Jet, Jynx gets a Shadow Claw, etc. Any Rock or Ground types get Aqua Tail/Jet, or just get shut down by Hypnosis.

What does this offer over other physical water attackers? Such as Qwilfish, for example.

I'm not saying it's a bad idea, I just think you should write how it's helpful to a team =).

I'm pretty sure I wrote a Choice Band set... exactly like this.
