How to play yorcik mid game. Build guide.

I have played lol for I think 7/8 years now.
I mailed adc for the most part but recently wanted to try Yorcik and it’s so much fun not to die so fast.

I usually win early game but in mid-late game idk what I should be doing and usually opponents scale harder and kill me even if I have more items. And I think I build wrong items.
