And late game swap Righteous Glory for Blade of the Ruined King to increase your already amazing dueling potential and your push, and your sustain, and your chase.

The only problem im seeing with this is the lack of righteous glory and the berserker greaves. You're typically supposed to build berserker greaves on the tigerdyr, the udyr build solely on attack speed and tiger stance. Ionian Boots of Lucidity with alacrity will speed up your clear time by taking you from 20% cdr to 35% cdr meaning you get more procs off the spellblade from triforce. You can make up for that attack speed by running attack speed marks. Moving on to Righteous Glory, that item gives bonus mana and health whenever you get a level up making sustain in the jg super easy to get fed, farmed, and overpowered super quickly; because between righteous glory and trailblazer-cinderhulk you're pretty much unstoppable in the jg not to mention how good the active is in team fights. Finally I dont see Randuin's Omen on your list. Full build: Randuins Omen, Black Cleaver/Righteous Glory (Black Cleaver if Super fed, Righteous glory if behind or playing average), Spirit Visage, Trailblazer-Cinderhulk, Ionian Boots of Lucidity-Alacrity, and Trinity Force/Blade of the Ruined King (Triforce for team fight team comp, BORK for a split push comp) makes you pretty much unstoppable because you're split pushing and working the gates+your overall tankiness+your sustain= winning by taking objectives and your team winning fights without you because they're going to send 2 or more people after you (and your team should be able to 4v3)+ carry ability because ive soloed barron a few times with builds similar to this. while your team pushes you can solo baron.
