• Focus on getting as much CS as possible
• Without Master-At-Arms and Trinity Force you won't be dealing a lot of damage - trade only when Counter Strike is available and you're not way ahead
• Look for opportunities to Teleport-gank mid or bot

Depending on your team composition and the enemies there are multiple ways to contribute to team fights

• Peel for your carries
• If you have a dive comp initiate team fights with Counter Strike to allow your team to shred throuh them
• If your team is far behind focus on split-pushing

• First, activate Counter Strike
• Jump onto the enemy with Leap Strike
• Activate Counter Strike another time to instantly stun the enemy
• If you have Tiamat or Titanic Hydra, activate it now
• Follow up with an auto attack
• Use Empower to reset your auto attack and deal more damage

If the enemy is still alive follow up with auto attacks and your abilitites as they come off cool-down.

Teemo: Rush Hexdrinker and Blade of the Ruined King, max out Leap Strike, go for quick trades, Quicksilver Sash might be necessary

Jayce: Similar to Teemo, rush Ninja Tabis and play the lane like Teemo

Pantheon: Start with Cloth Armor and 4 Health Potions, rush Ninja Tabis and go for health options like Phage and hope that your jungler supports you as much as possible

Fiora: Rush Bramble Vest and stack health, use reactivation of Counter Strike

Riven: Similar to Fiora, but a little bit easier in more than one aspect

Malphite: Rush Blade of the Ruined King, concentrate on farming, never trade unless your jungler is there or he's really low on health without his ultimate or Flash - usually, you have to rely on the base damages of Leap Strike& Empower

Irelia: Stack health - you beat her after Level 13 so farm until then and hope that your jungler helps you out

Garen: Time your Counter Striketo avoid his silence, but even then you have to be aware of his spin; he will regain health if you don't play aggressive enough - farm-up and wait for ganks

Cho'Gath: You need to destroy him before he hits level 6 - you need to set-up the wave so that it's not always pushed, make him work for CS and punish him as much as you can; rush Blade of the Ruined King

Singed: He counters Leap Strike and Counter Strike and is too tanky - chase him if he proxies and farm-up over time, rush defensive AP items (e. g. Adaptive Helm) or life-steal items to handle him proxying; never focus him in team fights, peel for your backline instead
