I think you're underselling Ursaring. While inflicted with status, Jolly Ursaring hits 538 attack, and 343 speed. To put that in perspective, that would be like a Pokemon that had base 105 speed and 157 attack holding a Life Orb, with a base 140 STAB move to throw around, and all the coverage it could ever want.Usaring gets Guts and Quick Feet as well as having STAB Facade to throw around. Too bad it has base 55 Speed.

Also, not sure if anyone thought of Cinccino yet, but Tech+Skill Link is INSANE. That's 187.5 base power attacks coming off of a decent attack stat, one of which gets STAB.
