To the above two posts. The reason why these pokemon were moved down into UU is that while being discussed they had Average-Low opposition (I'm also sure there is a list somewhere of the list of all of the pokemon that were discussed).
It's in the back two pages. The ones remaining, (all of which I highly oppose, except perhaps for Tauros) are:
- Marowak (High/Average)
If this thing gets any speed at all behind its belt, gg. It has ok defenses for a sweeper, and with some investment, will be able to take some hits (investment away from its unsavable speed). The myriad of Speed passers in UU don't help matters, and if played well, Maro is an absolute beast. If anyone says Claydol is a counter, I'm going to laugh at you and direct you to one of my warstories:
http://www.smogon.com/forums/showthread.php?t=32798, in which an uncanny bitch
Ice Beam and Reflect Claydol that held me up for half the match meets its end at the hands of an SD Double-Edge (mind you, a counter must be able to switch in with little or no risk to itself, and this demonstrates the scenario in which Maro got an SD on the switch, then Claydol dies). The next turn also features it surviving a (presumably Specs) Moltres' Flamethrower because I ran a bulky spread, so please nobody argue it has paper-thin defenses (I proceeded the win the match after I discovered the Crobat had Cross Poison over AA, but of course I would have had no chance at all if Maro didn't survive). In fact, what makes Maro so dangerous is that when it gets the appropriate switch-in, almost nothing can stop SD + Thick Club, which as everyone knows puts Choice Band to shame. It doesn't even need to set up to sweep, though SD makes it all the deadlier. Not even Weezing will be able to handle SD'd hits too well, a max defense one taking
78.74% - 92.81% from a single SD and OHKO if the user decides to gamble and hope for a crit from Stone Edge. The bulky waters and Meganium must exercise caution (the latter is screwed if Fire Punch is run, but this is extremely rare outside of OU). The best counter could perhaps be Rotom, who will need to be wary of Stone Edge. It packs a useful immunity to T-wave, and WoW isn't too reliable to stop it, because it will still be a formidable attacking force since either Thick Club or SD will help neutralize it a bit. As a Marowak user, it is not UU material by any stretch IMHO, and I oppose it.
- Tauros (High/Average)
Intimidate and 75/95 physical defense eases switch-ins, and it's a little cheaper to use than other UU sweepers, but it can be stopped. The jury's out on this, I guess.
- Regigigas (High/Average)
Another one I highly oppose. Even in BL, this thing is a bitch to take down, and I'm usually stuck in the scenario of switching in Steelix, whittling its health down a bit, and PHazing it away before Slow Start's time's up. I know realize this method was pretty stupid, as Knock Off gets rid of its only method of recovery besides Wish supporters. But that's how UU's #1 Pokemon will fare against it. Remember that Slow Start on halves Attack and Speed, and only hampering it from blowing away your team. In the meantime, 110/110/110 defenses, Thunder Wave/Knock Off to cripple things, plus just enough power to give some of your fragile set-ups (i.e. Scyther, Absol) and Subs trouble. Plus...what's everyone saying? "The end of fighting dominance"? Well, then I'd say to take this out of the list of things considered for UU, or everyone should stick subbing Cursers on their team (i.e. Miltank).
Note that of these, I've only actually used Maro. =( So find flaws with the latter two whatever you want.
