I tried this team on Shoddy. I found VERY few UU matches, but won virtually all of them except one vs Shiny Oddish (ODDish, whatever). He got me when Clamperl's Ice Beam did not OHKO Parasect and I got Spored. Even so Scyther managed a late game sweep, and it ended 2-0.

Unlike in OU, setting up Clamperl early on is not a bad idea. Clamperl can 1-2HKO every single pokemon in UU with ease. If I think my opponent will switch, or in some way ward off Hypnosis I just Trick Room outright. I might remove Rain Dance, since I rarely have the time for it. Maybe a nice Ice Beam or Stealth Rock instead.

Does a similar job as Lunatone, yet it has physical defense instead of special. Unlike Lunatone, I will keep this alive if posible as it can actually kill things when it needs to. Focus Sash helps with random stat-uppers, as it lets me fight off Nasty Plotted Ninetails and Swords Danced Pinsers.

Basically a poor man's Bronzong. Earth Power kills the UU steels (Aggron, Bastiodon, Mawile, Probopass). Rain Dances, Trick Rooms, then Explodes when I deem the time is right. In UU, I don't need to scout for Blisseys. I don't know what the EVs should be for him. Whatever lets him take the most threats in UU since he's my final Clamperl setup poke he needs to be the most reliable.

As strong as this is in OU, it rapes so much harder in UU. Clamperl 2HKOs everything, if not outright OHKO. Actually, Quagsire is probably not 2HKOed since its immune to Surf. I don't have much to say here that I haven't said in my Clamperl discusion page.

If I had this when I fought ODDish I might have had a chance to wake up Clamperl. Anyway, it counters the bulky waters mainly Quagsire. Toxic helps with stallish pokes, and can do the slight amount of residual damage I need to get OHKOs with Clamperl. Pretty damn bulky, it can stall teams by itself. Good for crippling defenseive pokes that are 2HKOed by Clamperl.

Subs on the switch, or to counter status. Swords Dance quickly turns this into a rape machine. Usually the last pokemon I send out, it is used for cleanup. Stealth Rock pisses him off, but its never stopped me from sweeping with him.
