In lane, try to save mana. You can get 10 mana for free if u hit an enemy champ with w, then q or e. You will need mana to q minions, especially if they zone you. Buy Sheen 1st back if you want poke in lane, Pickaxe if youre ahead and Tear of the Goddess if you lose lane. Once u have Muramana completed, you oneshot adcs. Iceborn Gauntlet is good for kiting and armor and is cheap, you should only go Trinity Force if youre ahead in the first 15 minutes. Duskblade of Draktharr is good against squishy team, Youmuu's Ghostblade to dodge skillshots and MS. Blade of the Ruined King and Death's Dance are always good options, but you should always have 45% cdr/40% cdr. Last Whisper if enemy stacks armor, Black Cleaver if u have 2+ ad champs on ur team who dont have Black Cleaver, and if enemy is stacking armor. Do not build Black Cleaver with Trinity Force.
