I made this a while back in my UU team and it used to suprise the opponent well, but it didn't work JUST because of this. It worked as a sweeper anyway. To check it worked for other people I also got Caelum to test it, and he approved.

<p>Kabutops' Special Attack isn’t spectacular, but it can be used to take out many common walls with rain support. When Rain Dance is set up, Surf will OHKO standard Skarmory and Weezing 79% of the time, with Stealth Rock. Hidden Power Grass will always OHKO standard Quagsire in UU, often opening a sweep.</p>
<p>With Rain Dance, Surf will easily OHKO many other physical walls in the UU metagame, such as Aggron and Steelix. Surf will do a minimum of 71% to Miltank, whilst a normal Life Orb Waterfall would top at 54%. Waterfall is here for physical rain-boosted STAB. Rain Dance goes in the last slot because it is vital to this set, but if you have support elsewhere Stone Edge will still OHKO Altaria and Mantine with Stealth Rock, who otherwise wall this set easily. X-Scissor, on the other hand will often 2HKO Meganium, and seriously dents Celebi in OU. Try to use Rain Dance elsewhere if possible though, for Stone Edge / X-Scissor's coverage will be greatly appreciated. Whichever move you drop means you will lose out against something, as without X-Scissor Meganium and Celebi wall the set, and without Stone Edge Altaria and Mantine will do the same. Venusaur and Vileplume won't take much from X-Scissor either, Stone Edge will be needed to do anything to these.</p>
<p>Stealth Rock support is vital, ensuring many OHKOs and 2HKOs. 84 Speed EVs outspeed Scarfed neutral base 95 Pokémon after Swift Swim.</p>
