Yeah... Twitch the best in my opinion he is good to gank, like you can see after feeded he become a pure assassin. Let's see.

In the runes i've put basically, in mark, the red ones, cd(critical damage), in seal, the yellow ones, as(attack speed), in Glyph, the blue ones, as(attack speed) finally in Quintessence, the brown ones, cd(critical damage).

In masteries basically ad, in my opinion the best.

With these items i made 39/4/11 and i think it's good enough to kill someone, in some cases i tried do 1x3 and i have sucessful because of the executionare, which gives life steal and phanton which gives attack speed. But never forgeting the attack damage and critical, which is important as life steal and attack speed.

I made this skill sequence first the stealth, to see if someone is hidding in the plants, if have someone it's very good for u to kill them with ad in the same lane, like shaco or yi, and this kind of champions. After We put the poison that is very good when they are running from you and make a good damage, never forgetting the slower skill that makes the guy slower and than u can catch him up and say "As té la vista, baby".

Basically this. If u have some suggestions and questions just write below and I'll do everthing i can for help or put ur suggestion in my build.

Thanks a lot for the viewers and gl hf for u all.
