I only aim to be helpful. Please do not feel offended of any criticism. I have enjoyed all three of your guides and like your formatting style. Just attempting to offer my advice based on the knowledge of the game I have achieved over the past 2 years.

I have a few concerns about your build.

I see you don't spec into Phoenix AT ALL until you have no where else to put points. Even if you prefer Tiger Stance, Phoenix stance is still very important to get early on and to put a few points into. If your lane opponent roams, your team is having trouble elsewhere, or you need to push early advantages to take early global objectives then you need Phoenix Stance. Tiger stance does good dueling damage but Phoenix can push a lane MUCH harder. If your opponent teleports down to a Dragon fight or something of a similar situation, you need pushing power!

You also don't get Bear Stance until level 4, which I feel is too late. Bear stance is your mobility ability, and the movement speed buff is your only form of a gap closer. You mention using Tiger Stance on an opponent who goes in for a last hit, well using Bear Stance on them when they go for a last hit and then hitting them with Tiger Stance while they are stunned accomplishes the same objective harass wise but ALSO makes them not get that minion last hit!

I also disagree firmly with your build option of taking Atma's over Trinity Force.

In neither build path do you show what you trade Wriggle's for late game.

You are not running Ghost or Flash, and Udyr is already notorious for having huge issues getting to enemy carries in team fights. He gets kited very easily and needs some sort of mobility steroid like Ghost, Flash, or Shurelya's Reverie.

You over-value the armor penetration quints. ALL of your harass is magic damage. Both Tiger Stance and Phoenix stance are magic damage. Flat Health Regeneration, Flat HP, or Attack Speed Quints would all be better choices.

You explain to reach 3 stacks of your passive prior to going in for harass, but you need to consider that activating Bear Stance when you go in gives you the 3rd stack, as well as activating Tiger Stance after bear stance, so really you only need 1 stack prior to harass.

Atma's Impaler does not fit well into Udyr's kit. Attack Speed items with bonus defensive stats like Wit's End and Madred's Bloodrazor are good. Mobility items like Shurelya's and Force of Nature are good. Defensive team fight items like Banshee's Veil, Randuin's Omen, and Guardian Angel are good. Trinity Force is CORE in your build. You can delay getting it and rush a Wit's End + Randuin's Omen combo, but before too long T-Force will still become a central item.

Nice guide

fsdf

Sheen> Phage because it gives a lot of burst with the activating damage of Wilding Claw, anyway this is situational and if you need more def Phage should be first ;) it is situational as usual.
The "trick" last hit --> Wilding Claw is nice ;)

A nice explained guide. Could you explain Sheen > Phage? Which to start with? Cause i always start Phage. Another thing, in lane, mention that when the enemy is going to lasthit, activate tiger stance and hit them. Every time it's on cooldown (Tho don't waste too much mana). But overall a nice guide.

ahhhhahah i hat it SO MUHHHHCCCC SO BAD U BADIE ME WANT OLAFA GUIDDD

Nice
