Hey Guys thats my first guide so sry for my English-SkileZz and it's maybe not the best guide.
But im a Pro, you will see how professional this guide is....

PROS OF Master Yi

- Alpha Strike ALMOST NO COOLDOWN IN LATE
- HIGH BURST IN LATE GAME
- ALMOST EVERY HIT IS CRITICAL
- EASY TO ASSASINATE THE ADC WITH Highlander AND Alpha Strike

CONS OF Master Yi

- WEAK EARLY GAME
- IN EARLY HIGH COOLDOWN ON Alpha Strike AND Meditate
- GANKS ARE NOT VERY EFFECTIVE BEFORE SKILLED Highlander
- COUNTERED HARD BY CC

Double Strike: IS A NICE GANKING TOOL FOR DEALING SOME EXTRA DMG. SO PREPARE IT FOR A GANK. TRY TO COMBINE IT WITH Alpha Strike.

Alpha Strike: ALSO VERY EFFECTIVE FOR YOUR PRE-6 GANKS. DON'T USE IT TO EARLY. RUN STRAIGHT TO THE ENEMIE CHAMPION AND ONLY ATTACK HIM WITH AUTO HITS. IF HE GET OUT OF YOUR AUTO HIT RANGE, CHASE HIM WITH Alpha Strike. (very effective)

Meditate: NO USE FOR GANKS. JUST USE IT TO HEAL YOURSELF BEFORE GANKING.

Wuju Style: SO I TOLD YOU NOT TO USE Alpha Strike TO EARLY. YOU HAVE TO USE YOUR AUTO HITS THAT YOU INCREASE WITH Wuju Style.

Highlander: THE MOST EFFECTIVE GANKNG TOOL. YOU JUST RUN ON THE LANE. CHASE ENEMIE
WITH YOUR EXTRA MOVEMNT SPEED. GIVE HIM SOME Alpha Strike. AND
DON'T FORGET YOUR Wuju Style.

IF YOU KNOW ITS WARDED YOU CAN STILL GANK WITH Ghost AND Highlander. ENEMIE WILL BE SUPRISED.

I THINK THE MOST IMPORTANT ITEMS ARE Statikk Shiv AND Infinity Edge. MAKE SURE YOU GOT THEM. SO WHAT YOU NOW NEED IS SOME LIFE STEAL. YOU GOT 2 OPTIONS. Bloodthirster OR Blade of the Ruined King. I PREFER Blade of the Ruined King CAUSE YOU GET SOME EXTRA ATTACK SPEED, WHICK IS VERY BENEFICIAL ON YI.

Phantom Dancer: ALSO GOOD ON YI CAUSE IT GIVES YOU SOME EXTRA ATTACK SPEED AND CRITICAL STRIKE CHANCE.

Trinity Force: LIKE PHANTOM DANCER ALSO TRINITY FORVE GIVES YOU ATTACK SPEED AND CRITICAL STRIKE CHANCE. BUT YOUR NEXT AUTO HIT AFTER USNG AN ABILITY WLLL BE A LOT STRONGER. SO A GOOOD TACIC WITH THIS ITEM IS: Wuju Style AVTIVATE --> AUTO HIT --> Alpha Strike --> AUTO HIT.

Mercurial Scimitar: I TOLD YOU YI GET HARD COUNTERED BY CC LIKE Infinite Duress, Nether Grasp OR "SHIIT" LIKE THIS. SO YOU CAN BUY THIS ITEM TO BE IMMUNE AGAINST THIS.

Frozen Mallet AND Warmog's Armor: TANKY OPTIONS FOR YI BUT NOT REALLY MY FAVOURITES.

Guardian Angel: THIS ITEM IS AWESOME ON YI. WITH YOUR DMG AND YOUR LIFE-STEAL YOU CAN GET EASY FULL HEALTH AFTER GA AND YOU CAN CONTINUE YOUR PENTA.

Wit's End: FEEDED AP IN ENEMIE TEAM? NO PROBLEM! THIS ITEM IS ALSO REALLY NICE WITH ITS MAGIC RESIST AND A BIG BONUS OF ATTACK SPEED.

Banshee's Veil: OK, THIS ITEM IS REALLY UNUSUAL IN MY BUILD BUT HEY, I HATE Final Spark, Trueshot Barrage AND THE LAST HORROR: Super Mega Death Rocket!.

Hunter's Machete: SELL THIS SHIIT AS EARLY AS YOU CAN. PREFERENTIAL AFTER YOU BOUGHT Statikk Shiv

SO... THAT'S HOW I PLAY MASTER YI IN JUNGLE. PLEASE GIVE ME AN VALUATION AND MAYBE A COMMENT AND SOME IMPROVEMENT SUGGESTIONS. THANKS AND BYE...
