Pregame

DO NOT PICK MASTER YI IF YOUR TEAM ALREADY HAS A SQUISHY DPS CARRY (ie twitch, ashe, shaco, etc.)

Summoner Spells:

Exhaust: The reason why I choose exhaust is slow someone that is chasing me or I am chasing. Another use for exhaust is to save your *** or give you the advantage in a 1v1 fight.

Cleanse: Cleanse can be used to get out of slows, stuns, snares, etc. and now, with the recent buff to cleanse, exhaust! This is huge, if some AP champ is running around with exhaust and bursts you to almost no health you can now cleanse out of the exhaust and melt their face before their spells come back.

Optional Spells:

Ghost: In combination with Highlander and Youmoo's Ghostblade you can get some EXTREME movement speed. (Can be used to escape or chase, I prefer to use it to escape.)

Ignite: Can be used to change those "OH SO CLOSE!!!!" failed tower dives to "ZOMG I'M DOING SO MUCH DAMAGE BECAUSE THEY FED ME!!!!!".

Flash: An obvious escape mechanism.

Stay away from:

Clairvoyance, Fortify, Revive, Rally, Smite are all useless if you follow this build and should be used by other champions.

Stages of the Game

Early Game - Level 1-6: Stay back behind your melee minions and last hit the enemy's melee minions. Use alpha strike to attack the mage minions and enemy champions.

Mid Game - Level 6-12: After purchasing your Youmuu's Ghostblade ask your lane partner to start becoming more aggressive, when the time is right Alpha Strike -> Enable Highlander -> Activate Youmuu's Ghostbalde -> Enable Wuju Style -> Exhaust -> Profit -> Repeat.

End Game - Level 12-18: If you've gotten a couple kills, haven't gotten killed a lot, and have farmed a decent amount, it's time to start dealing some massive damage. Before teamfights determine who has the most lethal combo and wait in safety for them to use it. After they use it, Alpha Strike -> Enable Highlander -> Activate Youmuu's Ghostblade -> Enable Wuju Style -> Exhaust highest PHYSICAL damage dealer ->Repeat until they all die
