Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Summoner Skills I use the flash spell to kill or to escape (with the help of the ambush). My second summoner skill is teleport[ because i can surprise the opponent (with the help of the ambush)
Early game At the beginning you must be careful because twitch is an easy hero to kill, so try to avoid heroes with stuns or taunt... but not be afraid because twitch also gives damage!
Mid game Now you have teleport and ambush and you can surprise any opponent and make a kill
late game Enjoy your twitch and try to make a penta kill with him!
Sorry but my english sucks and this is my first guild :) vote and enjoy
