Lets go straight forward:

RULE 1 : You hate early and mid game, because you are totally useless.

RULE 2 : You are not a fighter, you are an assassin.

RULE 3 : You are a turret destruction machine.

RULE 4 : You don't engage in a battle to save your buddies, you engage to killsteal ( ks means: finish an unfinished job) your team mates.

RULE 5 : Use your Ult whenever possible on minions to farm.

Quoted:

Why attack speed only runes?

Answer : Because I said so.

You need survivability.
For moving fast between the lanes.
Damage.
Attack speed that will make you a turret killer.
Upgrading your
You need health to kill a turret and things get better after you upgrade it to
More attack speed.
Upgrading your first item.


Having all your items, your item slot will look like this:

Follow the rules.

Just wait untill late game because it is when you become usefull. Meanwhile just farm. Use your Ult for it.

Don't engage in a battle to save a team mate chased by 3 or 4 enemies. Just let him die and watch if there is anyone with low-health.

Don't useExpunge too early. With full stacks you can deal more damage and have a certain kill.

Aways check your enemy jungle area. If you see someone jungling, don't show up - call your team for a gank, and don't let they get the kill: you must ks them.

Ks'ing is your job. Don't worry if they start *****ing and whining.

Don't die for a kill. Only do this if the one you going to kill had achieved a " god-like" or something.

If the enemy getoracles and you can't kill him so easly, stay away from him and try to get some turret or dragon. ( You will surely die if you engage in a team fight with someone using oracles ).

Don't try to killTeemo. You will die if you ever try 1 vs 1 on him without any advantage.

Backdooring will be your main ocupation during the game.

You have stealth, You have attack speed, You got Frozen Mallet, so go and BRING ALL THEIR TURRETS AND INHIBITORS DOWN because this is the only thing POST-NERF TWITCH can do right!!!


GOOD LUCK.
