The Re***on i have taken these runes is becasue of more AD-(attack damage) AS-(attack speed) CC-(Critical chance) CD-(Critical Damage) with these runes u will have a good start from the beginnig and probaly love afterwards.

Acatully the masteries are up to you! The Re***on i choose these masteries is becasue MF(Miss Fortune) is pure AD-(Attack Damage) AS-(Attack Speed) and etc... well in my eyes she is and you should also notice that i have taken some mana reg at utility it does not help very(x5) much but it helps you out alot

I must admitt that i have been using an another guide that has a few of my ideas:
http://www.mobafire.com/league-of-legends/build/miss-fortune-a-detailed-guide-150521

i used the guide for like 5-15 times then i figured out that i wanted to try out my own build like
2 PD-(Phantom Dancer), 2 TBT-(The Blood Thirster), IG-(Infinity Edge). for i must say it was like i was the devil or someone from hell becasue i had a sick life steal! but OFC-(of course)
i also found out this... u can sell one or two item(s) but which one of the weapons is up to you. replace the item(s) with ''Warmog's Armor'', ''Thornmail'', or ''Guardians angel'' if u want to replace any of you're weapon(s). but as i sad i feel like the devil when i use my own build!

One of the re***ons i took that skill sequences is becasue ''Impure Shots'' gives you more AS-(Attack Speed) but you have very/good AS

Flash and Ignite are very good opinions becasue first of all

1. Flash can be used as an escape tool or killing tool for example: let's say you're being chased across the whole map by the whole enemy team and you're running like hell (or not) toward a wall that dosen't mean ur dead or stuck! u can flash over the wall dude(or else where)!

2. if you're team is chasing an enemy and they can't reach for him and none of them has flash and u do then u can flash forward and grab the kill simple as that is it!

1. Ignite can prove it self very handfull! let's say you're in the middle of a fight 1vs1 and you're opponent and you are both on low health then u can use it to save ur life becasue it lowers the healing income on you're enemy so you may kill him right away

2.when you're opponent is running away from you use ignite it lowers the healing income and second of all it kill you're enemy that simple is that one to

OOOHHHH WAIT!!!
try out flash and ignite i promise u that u won't regret it just try it once i can promise u that u will kill an enemy or escape one with both flash and ignite TRY IT OUT!!:'D

Pros
1. can easily farm gold or money
2. Shes a ranged champion
3. has a slowing ability MAKE IT RAIN!!!!
4. has good MS-(Movement Speed) at the start
5. can kill an enemy easliy with one hit at the earlie game mid game or late game with very very low health
Cons
1. Squizy
2. ulti needs to be postioned good
3. she can often be the most ''wanted'' champ to kill in the game
4. make it rain dosen't last long

MF's(Miss fortune's) make it rain ability can save some of you're team mates life's or you're own life

MF's(Miss fortune's) make it rain ability and double is an good combo for farming takes a little bit of mana but workes very good
