If you can time all right this build can be really powerful in 1v1. Also its pretty easy to escape from almost anything, especially after you get rewind. REMEMBER you aren't invicible, while you are in stealth it leaves that ripple, so if opponent catches you while your cooldowns are down you'r pretty much dead. With this build you are supposed to move pretty much all the time, to avoid getting caught. Take your time to get perfect situation before striking. I don't really have much else to say about it so hope you like it. :)

Rapid Displacement well... your blink cooldown is lower and that is good.
Vorpal Blade is pretty much the whole idea of this build with Wormhole.
Follow Through is good since you will use blink so often.
If you need more health go for First Aid
Level 10 talents both are good, take Shadow assault if you want more damage and Void Prison if you need more ways of escaping.
Wormhole is the other big factor of this build but can be replaced with Assasin's Blade if you absolutely need more damage.
Rending Cleave is good since you usually don't want to stick to your opponent for too long so that'll give some free damage while you Blink away.
If you need more sustain go for Stoneskin or if you need extra speed and attack speed go for Berserk.
Rewind gives you back Blink and can help finish with burst attack in form of: Singularity Spike to Cleave.

Pros:
Good in 1v1 if you time all right.
Good at chasing and finishing.
Good mobility.

Cons:
If opponent sees you through stealth and you have your cooldowns up it can be real pain.
Low health if you get caught.
Easily bursted.
