Ive been playing alot of builds, none of which i like. So i made my own which i seem to dominate with. I usually Get 300 ping so focusing AP isnt very good as skillshots miss abit.

Runes -
Armor pen is win :) i like the dmg against "tanky" champions, i find it helps alot.
Cooldown reduction helps with dps skill shots.
MP5 Allows for almost constant skill shots, optimizing AD dps items.
Quintessence's
Health is good at early game, Ezreal is a VERY squishy champion, however some people prefer DPS (arp) or the speed increase for survivability.

Masteries ---
Offence -
Crit is best for AD, 1pt AP cause nothing better
cooldown reduction is good for dps / surv
atk speed is mad for AD, want that
Ignite is pretty hot, mad dmg with talent, also reduces healing 50%
Sunder is mad, allows for rapage
atk dmg is good
Crit strike dmg isnt so great with this build, so i ignored it. should only have 2% UB or 12% at lvl 18 with gears.
5% base dmg is good :)

Utility -
health and mana regen is cool face for laning longer, getting more exp etc. may save lives.
Reduces time dead, i know right. Squishy stuff happens.
Exp boost is good exp since u should solo lane and are carry champ.
1pt in buff duro cause they help late game. (even if u dont jungle <slaying nubs>)

Items ---
I always go for the Occult 1st. Some games i get 20 stacks which just rapes things.
so i get hp pot / sword at start. Mp5 should be covered by runes and u want to lane longer for more sexp. I usually get Occult around lvl 6. This is prime for Ranged map kills to give more stacks for occult.
Nest on the list is boots. Depends what team comps are, might go for merc threads or beserker threads.
After this i want blood razers cause of the dmg out put against any champ (expcially tanks)
After razers i get Malady because it reduces mgk resistance and gives 20dmg and atk speed.
This is good because Razers deal mgk dmg. therefor increasing dps. and speed is good
Then i go for cleaver for sunder arp dmg. Depends on how the games going though. If i feel like im lacking speed, stack speed for razers to rape.

Skill Sequence ---
1 of each to start off with. need mystic shot to dps, then arcane shift to escape / line up and dmg targets. 1pt for essense flux dmg burst at low lvl, and if lined up for multi hero hits for dmg / debuff or ally buff.
Get ultimate when u can. Is goooood.
I usually max mystic shot 1st, i likes dmg output.
Then i max arcane shift for dmg / escape / line up capabilities.
Mystic flux is last because of the smaller range and useless ness against creeps / ranged heros cause it doesnt reach far.

Summoner Spells ---
Ignite and Clear voiance.
Ignite has mad dmg / healing reduction. that simple!
Also CV for random map checking / gank checking and or Fog of War True shot barrage Finishers

Summary ---
Mad dps. good if ur abit laggy. Universal and can be altered abit for ur enjoyment.


Hit me up if i spelt something bad. just a quickie for u lads :)
