His E, when combined with his Q attack speed increase is a force to be reckoned with. He can get multiple early kills with this combo (and a decent Support if he is ADC). When in the Jungle, the Red Buff can amplify the effects of this combo.
His Ultimate R and his Passive allows him to shred through the enemy team with ease when they happen to be grouped together. This gives him a very strong advantage in choke points.
He can use his Q to scout around and set vision for his team as well. Besides that, his W allows for some crowd control set-up for his team which they can follow up on.
Extremely squishy and can be easily killed if he is CC’d. His positioning matters in team fights as well, otherwise, he can get flanked by enemy assassins and get instantly deleted.
Without his Ultimate R or Q, his ability to dominate a team fight drastically decreases. Fighting him during this stage will give the enemy team a much greater chance of winning.
Practically gets countered by a Control Ward as it forces him to reroute. This is because of the short-ranged nature of his auto-attacks, which makes him get detected quite easily.

Play safe for the first few levels. You need time to come online and you shouldn’t be fighting unless you have a clear early advantage.
After destroying the bottom lane tower, rotate to the mid lane and try to take that tower. This will open up the map and give your team a gold lead.
Once you have a few levels under your belt, you can start to play aggressive and look for aggressive plays. You benefit from extended trades, so try to go for them frequently.

Try and stick with your Support throughout the mid-game. You’re quite vulnerable and easy to kill if you’re on your own. By staying with your Support, your survivability will increase.
Continue picking up farm in the side lanes when no team fights are occurring, but spend as little time away from your team. You need gold and XP to buy items and if you fall behind, it will be unlikely that you’ll be able to dish out damage in fights.
Look for picks with your Support/Jungler to get kills and increase your lead. If you kill a key target, you could make the call for Baron.
Just like in the mid-game, you should stick with your Support throughout the later parts of the game. Do not go around the map alone as you will die easily.
Do not play super aggressive in team fights. Just kite and auto-attack the nearest enemy champion. If you walk too far forward, the enemy will focus you and take you down.
Continue to kite in team fights and consistently adapt your positioning. Avoid standing still in fights as you’ll be an easy target.
Twitch's early game is pretty strong as he can poke enemies down with his E while slowing them with his W. The lane brushes will help him a lot.
Level six is a colossal power spike as it allows Twitch to impact and disrupt fights massively. It will be a devastating tool in clumped fights.
His first item component will increase his dueling potential significantly. His ability to dish out damage in the lane will also skyrocket.
His first ability will be maxed out at level 9. This will significantly boost his damage and let her one-shot squishies if they take many auto-attacks from Twitch.
Once he has 2 points in his Ultimate R, he will easily be able to take over team fights and disrupt them as well. His positioning will matter a lot.
Twitch is really good in mid-game fights as he can overrun the enemies down if they are clumped together. That, combined with his W slow and life-steal, will prevent him from dying.
Three points in his Ultimate R will give him a huge power spike. The ability will be up frequently, allowing him to secure picks when possible.
His life steal and damage during the late game will make him really good in team fights. He will just need to maintain proper positioning and use his Q and E at the right time.
He will have multiple items during this phase of the game. It will allow him to dish out tons of damage. Prolonged team fights will see him winning effortlessly.
