This Champion has alot to give and I'm here to share what I have found that works and havn't lost a game with her yet! *Hint* Havn't LOST yet...(I know I will get a feeder sooner or later but yea...) I hope you take the time to read it and please inform me with your oppinions. =) Have FUN!

These are some games I have tested and won real games with recently.
RUNES
The Rune page is not working for me apparently so I will tell you here.

I put Armor Penetration in Marks.
Mana Regen per lvl in BOTH Seal and Glyph.
And more Armor Penetration in Quintessence.

Pros
-She has extreme range.
-Great Immobilizer
-Great against gank fights
-Can deal some sick damage
-Criminals always hate the Sheriff...

Cons
-Squishy
-Can struggle with Mana if not careful
-Can be an easy target for dps's

I go with a 21/0/9 for more crit damage, and physical damage output and still be able to escape,regain health,mana and also level up faster.

My summoner spells are Ghost and Clense because even though her 90. Caliber Net is a great escape method...it only slows down one champion leaving the rest of the gank to chase you down.

I find that these items (in a very accurate order) works every time IF you play smart.

This Champion I find as a great lane partner but also a solo mid. For now I'm going to talk how to play as her as a lane partner for now.

Early:
You start with buying a Doran's Blade. Gives you extra health, dmg, and lifesteal. The main thing with her is to try to control the bushes with your lane partner. It's basically a must with her since her passive allows you to do headshots more often. Don't let the enemies take control of the bushes! Next buy Berzerk Shoes which will give you that extra attack speed and movement that is a must. By now you should be getting close to lvl 6.

Mid:
Here's the thing with mid game if you have enough money to buy B.F. Sword THEN BUY IT! If not go buy a Vampiric Scepter. You should start working on getting your Bloodthirster. I know some people ask "Why not the Infinity edge first?" It's too early in the game to get that kind of money and Bloodthirster substitutes the Damage you want from an Infinity Edge. Next work on getting your Last Whisper. After this you should buy the Elixers I have listed so you can kill champions and earn that gold you need.

Late:
Ganking has already been happeneing and hopefully your team is pushing good. You should try to stay behind your gank as much as possible since you're squishy and easy bait for Nukers or DPS. You should buy another B.F. Sword if possible and build your Infinity Edge. Then work on your Banshee's Veil because usually every team will have some kind of CC or "Magic Johnson" on the team. Pop Some more Elixers and work on building w/e you feel that is needed next that I have listed OR your own personal desicion. I have never played a game to where i had to buy a 6th item yet so this is why I have them listed.

-Frozen Mallet (More Health,DMG, and Slow enemies movement speedon every auto-attack)
-Madred's Bloodrazor (Great Tank destroyer who has a lot of *Health*)
-The Black Cleaver (Great Tank destoyer if they have a lot of armor)
-Bloodthirster (Way more DMG than Frozen Mallet, and Lifesteal)
