I'm probably going to be a joke, but did anyone try Dragon Dance Dragonair? (Shelgon has higher attack but lower speed)
Dragonair @ Life Orb
252 Atk 252 Spe 4 HP
Jolly nature
Shed Skin ability
-Dragon Dance
-Outrage
-Waterfall
-ExtremeSpeed
This acts like Latias from OU, only a physical one. Outrage and Waterfall are excellent options, as it allows you to hit those pesky fires that are going to dominate the tier like someone here said, STAB Outrage further boosted from LO is a complete menace, as the lack of steel types to come onto you is a huge advantage, so being locked onto Outrage isn't bad at all. ExtremeSpeed completes the set so scarfed things won't piss on you.
It has a pretty shallow movepool but it can be utilized, if you think ES is unnecessary Thunder Wave feels like a fine option.
What makes Dragonair a good choice is that it resists fire and can hit them with SE +1 Waterfall, which most fires won't enjoy.
Another weird possibility is Taillow and Larvitar, Taillow has decent speed, and Larvitar can both abuse Guts AND have Rock Polish, making his redicolus 199 speed into a blazing 398.
Like I said they are weird and it didn't sprinkle to my mind that Urasering outclasses both.
By the way, is Sneasel any of use? Despite Fires running rampant, not all are scarfed and Sneasel might actually do something to them.
