Is there any counter play to sated master yi?

The enemy had 4 ad champs including master yi so i picked malphite top. He was not fed and barely ganked trying to get stacks. at around 40 minutes in he was 8-10 but had sated devourer,bork,scimitar, and boots. Me, playing malphite against 4 AD champs had 670 armor, frozen gauntlet, frozen heart, randuins, thornmail,ninja tabi, and abyssal sceptor thinking those 5 items would shut him down. So i was steady pushing top and out comes yi. so i wait until he alpha strikes and then do the E and turn on my W and start slapping him. i lasted 3 seconds. he chopped me up. he did 1100 true damage with wuju style and didnt lose an ounce of health. how do you counter play yi? and dont say "your a bronzie he is easy" im gold 2
