So here is my build for master yi season 8 update! Let me know what you think, and just test it in a game and see if it works well.. Thank you guys..

JUST REMEMBER GUYS... HARD CC CHAMPIONS ARE HARD TO KILL WHEN YOU ARE YI... And also if you want some tips and tricks watch the Real Master Yi main. Cowsep! :))

Full Build order:
For now full crit is the way to go now, as all champions are into one shots especially zoe. Not a real threat to master yi though. However if you get hit by the "asleep" skill, no one is safe on zoe. Today's season is to one shot or be one shoted if that is even a word haha.

At first your going to have to work on with the first level skirmisher's sabre only, no enchants or anything, you can also use stalker's blade if you want. Then work on your trinity force. Trinity force is for the additional movement speed at autos and sheen proc one shots as well. After that work on your boots and stattik shiv or your enchantment depending on the situation, then if you're fed enough, go with Dusk blade, and if not, go with infinity-bloodthirster-duskblade. Then you can one shot or either 3 to 4 shot somebody without having any trouble with MS.

DARK HARVEST is what I prefer as keystone mastery or runes or watever XD because as you alpha,the sheen procs then stattik shiv doing some work and duskblade+dark harvest. Just work on the stacks though, that's for sure. Average stacks per minute 15: 50-70 stacks... minute 20- 80-100 stacks... minute 30-100+ stacks.. That's it :)

I basically start with red, then wolves living the little one, then go for the blue and go back to the little wolf for extra XP then gromp. After that try to gank or do whatever you want.
