Finally tried Udyr in a normal game (tiger stance this time). We had a roaming Eve, so I was solo top. Skarner wasn't too bad, but Kayle actually hit pretty hard (her passive is kind of a ***** early game). I'm not confident with Udyr at all, and I had some issues with keeping sustained because I wasn't very aggressive. Once we got out of the laning phase it became obvious the enemy team was mostly ******ed. They spent most of the teamfights focusing on me and allowing my allies to kill them. It was kind of funny. By the end I could tank turrets with turtle stance and take no damage.

My build is probably terrible, but it worked xD
