How to win
Just take a little trade lvl 1 to proc your keystone, GG WP he's midlife with one AA and Q.
You just have to Q when he want to last hit. If it's a ranged champ. Wait your level 2 or 3. Just rush him with your E and do the usual combo then pick the shield and run back. Gg, you win the early game.
Try to push and if you think you can tower dive. DO IT, or just go in their jungle to give some problem to their jungler.
