Hi im a normal league player who wanted to show off skills ( yeah right with playing udyr).
Then i when to a ranked game with udyr without knowing anything to build so i ended up feeding and being bad.Then i started watching udyr players on youtube/twitch like trick2g.
And now if a game gets to lategame theres no way you can loose cuz GATES GOTTA OPEN!

You want to start with Gromp ( being the wight camp) and move to Blue sentinel ( blue buff for most of us) and after wolves go back to buy as you should get your smite upgraded then tp to nearest tower to Krugs( douple golems)->Red Brambleback (red buff for most of us)-> Razorbeaks ( wraiths)-> wolves-> Gromp ->Krugs -> Razorbeaks. If your team needs ganks You can go start withTurtle Stance to negate dmg they try to do to you and then stun them withBear Stance But keep running where they might go to do the most dmg and they shouldn't be able to get away.

Pros of UDYR:
-High damage late game
-Insane survivalability
-Easy ganks
-Tankynes is great for your team

Cons of UDYR:
-Can get flamed on if you just farm
-Enemy team might try to outnumber you (more then 3 ) but if they dont have any stuns you can just fight them if your team is coming or just run
-Weak early game
