Threats to Corki with this build
|Twitch||Not a particulary hard matchup, after level 6 you will have the advantage, try to trade him down with your abilities.|
Before level 6, it is not recommended to use any abilities for farming, becouse you will lose a lot of mana, which is really important for Corki to be able to stay in lane. After level 6, you can clear bigger vawes with your Q and R, just make sure to not do it that often, until you have a resonable amount of base mana.
