I don't think this is a good build. You just won't do damage with it. 2x PhantomDancer and 1x IE let you hit and crit very often, but with no AD you won't scare anyone.
Rated down.

copy build? lol

Honestly I dont think this is a very good build because you are very vulnerable early game with no CrC runes and even after they gave him a base crit chance, that isnt enough you really need the early game damage because in late game its harder to get really fed. but if your fed early game, you can gank, help teamates and its alot better with crit chance runes.

Not very... indepth is it?

Good enough build I guess, I'll try the tabis to see how they work out

very good build +1

GOOD BUILD I LIKE IT :) +1

I think that your sixth item should be either life steal (executioner's calling) or health regen (Force of Nature). =D +1

Very nice build, u can change the game with this build!

****py build. you need to get spin first for lvl 1 gank or to escape if they rush you for first blood. Banshees is kinda ****py on him cause you dont have mana and with your ult and spin to escape you shouldnt be dieing to any nuke casters anyway. i agree with the guy above me, if you are having survivability issues, get frozen mallet, or if casters are really hurting you, get spirit visage early game so you can own and they dont get buff(SV is good because of the magic resist, increased heal from your bloodlust and probable life steal item like executioners or starks, and reduced cool downs is good on anyone. also in higher elo games you will probably have heal bots)

Its a nice build,but i wouldnt take banshees just because tryn doesnt use any mana. try warmogs armor or frozen mallet,should have bettter effect than this :)

Well..
This build "could" work, but you're ignoring the damage till pretty much end game.
Banshee's veil should be a situational item. not a part of the build.
It won't work as good in all games.

And it is indeed pretty darn expensive.
At least put the Infinity Edge before the second Phantom Dancer. It really synergize with Trynd's bloodlust.

This is a pretty good and simple build. i would pref. a little more damage, but thats just my opinion.

You should rly try my Tryndamere Guide.. its awesome :)

Well +1 for your guide.
