I usually start by just poking the enemy and not engaging Intel they are low but mostly farming with parley intell i get phantom dancers then i start playing more aggressively because of the 30% crit chance then once i get infinity edge and the first executioners calling i i play fully aggresive attacking whatever champ gets near me but not to the point when your trying too pull of a trynd kill that doesnt work(trust me i know i tried) in team fights try and pick off the weakest and then finishing off the tank if hes still alive

P.S this is just how i play you can change it up if you want but this is how ive found my build most affective and i dont know why it says ull have so much attack speed at the end but itll only be 1.4-1.6
