Hey guys this is my first build so dont be too harsh but your comments will be appreciated and used on future builds. Good luck hope my build helps :D

Some twitch build will tell you to get an infinity edge before you get your phantom dancer and I think you need to get the phantom first because it cost less and hekps you more early game before you get your infinity edge.

I got with major attack speed on my marks and glyphs...this will help with twich being bad early game for the seals I go with health over levels so you get even better late game so you can dominate over your enemies for more than one enemy and need the extra health to secure that final kill. For my quints I go with crit chance so i get my crit chance to over 100% by full buld late game so i can do major damage to enemy plays and get quick kills.

The reason I use telelport is so you can stealth and teleport and be ready to get some quick kills, this build is going to build you mid-late game becuase as twitch you cant really be all that good early game but the damge he has late game will destroy most targets you can come into contact with and youll be a major menace in the late game. youll be the dominating factor for your team and will lead them to victory.

I use flash so you can get away easy form your target if you get in a tough spot and need a way out...this will give you the ticket over a wall or to a turret or teamate for help.

Alternates could include ingnite, for the extra dot to go with your poison or you could use exhaust to go with your slow and get that extra damage on them when they try to run away.
