Hi, seeing the high AD ratio on tryndamere E and the new lethality items , I tried make it work !
You will get high AD, high lethality, high crit & high crit damage with quite a bit of CDR and movement speed too !
With Ghost, Youmuu and your E you should be able to stick to your ennemies and cut them into pieces.
The cons are : no attack speed exept for the boots & runes.

Explanation :
Runes : Lethal Tempo for attack speed, Transcendance for some life-saving CDR after kills.
Boots : your only source of attack speed.
Voltaic-cyclosword : give your everything you need (except AS) : damage, lethality, CDR and a nice slow to stick to your ennemies
Alternatively : Opportunity for more mouvement speed but less CDR
Youmuu : cheap lethality with high damage which give you increased movement speed to never let anyone escape your rage
Navori : crit, damage and CDR sounds good at this point of the game
Alternatively : get collector if you don't need more CDR and/or they have a lot of tanks
Dominik : some % lethality, some damage and even more damage as you didn't build any HP, even tanks will melt
Alternatively : get Mortal Reminder if they dont have tanks and/or have high sustain
And finally Infinity Edge : now that you have 100% crit chance, let make your crit deal even more damage !
