1) Twitch can now recall invisible!!: Use Q and then immediately press "b" to recall invisible!
2) Twitch is a late game champion, but can take easily early kills if your support plays good!
3) Easy last-hit but it would take some time to get used to his early damage!

You'l have to be patient.Just farm and engage only when your support does.NEVER try to poke enemies with twitch.He is unable to poke especially in early game so just focus on farming and getting the easy early kills!

Back immediately when under 20% Hp!

Twitch is another ultimate late game hyper-carry adc. His play-style though is really different than the other one's.Once you prepare to fight twitch does not try to engage fast either go for quick kills.
He instead sneaks up his enemies using Q and R.
When your team goes for a fight stand BACK! Use Q go at middle range from your opponents and then use R and basic attack everyone this will stack your passive to any player and if your basic attacks don't kill them in seconds your E will then!
