With Talon, I find a lot of people going with auto attack builds, this build is more concentrated him doing his job "assassination", you go in get a kill or two, run out. You will want to use the combo starting withto proc your Sheen, this will cause to do massive damage being your next attack, then, to make sure they can't run, if they are still alive, use , this will keep them in range for your , for this all you have to do is press R, then ignite someone or flash away, and deal the maximum amount of damage, this combo if used correctly and mastered will take as short as 2 seconds, and you will be rolling in kills, while the other team ***** bricks because of the burst damage.

Pros:

Good damage after level 3
Tons of burst
Quick getaway skill
A slow
Gap closer

Cons:

Mana problem in early laning phase
Squishy if targeted
Easily zoned against ranged carries(AD or AP)
