I've been looking for a nice 3vs3 yi build to compare to mine, but tbh i don't find this one "the best"

In the beginning, it showed wriggles lantern after Berserkers greaves yet you never talked about it.

With my build, i won 4 games in a row with an average of 17-22 kills and average 0-3 deaths. This build is not straightfoward and does not truely explain what to do in different situations. Like what od you do with a team of squishies? Tanks?

With my build, i stay in the fight until i can get BG, and if i can push it, get Zeal right away. After that, i rush a phantom dancer. When the game progresses, i just hop from lane to lane, not killing many minions, and ganking heros left right and center. I usually call a gank witha stunner/slower then just hack them down.

At this point i get my bloodthirstier because it is my most vital part of the build. When i get this item, no matter how tough my opponents are, it is very hard to kill me. I farm Drag and Liz for both their auras and start pwning heros. I fought nunu, voli and ashe and i was with ashe and an AFK Warwick. We pwned the game 32-2. warwick joined 30 secs before they surrendered.

In that game, after bloodthirstier, i went L-W and Thornmail, because i hate voli. After that i got another bloodthirstier because they got Thornmail, so i countered with more LS. After that it was simply for giggles.

As i say again, this build is lacking and not that great, sorry to say :/

As mentioned MajorLoL this build is glass-cannon. No one will let you farm like this. Twisted Treeline games are just shorter. If you manage to farm 10K then its A LOT. My games with Jax mostly ends before I manage to finish third item (boots, TF, HG). Thats another point I want to talk about. Imagine you met Jax. Smart Jax, not just someone who tried him, because he is (was) free. He push E and laughs 3 seconds, then he Exhaust you and continue to laughing. These are 5 secs when you can do totally nothing and he wrecks you. Probly much sooner before Exhaust duration ends...

Never mind, found out how it works :D

Uhm, I found the exact same picture on Google, and I copied the URL I think, and then on MobaFire I Pressed "Image" and pasted in the URL. Them I Saved and Published, and went to the real site with the build on, and there was only this white paper mark /:

Well you have to copy the URL of the picture, say if i wanted to put up your avatar:
Did you use the pic URL? And if so, did you check in the editing draft or in the preview?

Uhm, I can't seem to figure out how to add pictures...
When i press the "Image" button and paste a link from Google, then on the "finished" guide, it's just a paper? Can you help me with this?

No, it's not complete yet :)
And I'll add some pictures soon, and make a more In-Depth view :)
Should I add a Gameplay Video?

The build is glass-cannon, you'll die in 2 seconds. I would recommend at least adding some type of survivability into the main build. I know you mentioned it, but some people wouldn't end up seeing it and go as glass-cannony as your build suggests.

Second add more pictures. The guides just a wall of text right now with no pictures to break up the writing and make it look more like a pleasant read.

Last thing, I think the guide could be much longer and more informative. Try adding a gameplay section and go more in-depth on what you should be doing with Master Yi. Right now the guide looks unfinished, tell me if I'm wrong.

If you can make some changes I'll give you a +1
