So while doing the whole NU Team Builder thing, I had a moment of realization. Hey, most of Samurott's counters get wrecked by Ice Beam (Altaria, Bulky Grasses). Not only that, but since most of the extra EVs got dumped into HP, why not just dump them into Special Attack? And thus, Mixed Samurott was born.
Samurott @ Life Orb
Torrent
252 Atk / 112 SpA / 144 Spe
Naughty Nature
Sword Dance / Aqua Jet
Ice Beam
Waterfall
Megahorn
Now the EVs are a bit assed, as they are just standard SD samurott EVs but with all of the HP EVs dumped into SpA. I also haven't gotten much time to try this set out, as the people I fight against in PS don't use pokemon Ice Beam is suppose to murder, and I have the new version of PO (it's horrible :( ) so I can't get into the Smogon Server, so most of this is theorymoning. However, I have used Samurott a lot and can say that it is amazing. The main problem this set has is lack of Aqua Jet means it's a lot easier to revenge kill. However, this set is less of a sweeper (although it can sweep) and more of a wallbreaker / lure. You could use over Swords Dance if you really want the priority, but I feel any physical Samurott without Swords Dance is an inferior Specially Offensive Samurott. Of course this isn't true because Mixed has access to Megahorn and Priority (if you choose Aqua Jet over SD), but I don't feel like that's enough to make it better. An interesting item that comes to mind that can be used over Life Orb is Salac Berry, as this allows it to have +1 speed when reaching 25%, thus helping out with the whole speed issue.
