Now i know that people use to build Ezreal as an ability power champion, after they buffed him and changed his AP to AD scaling so most people i see playing ez build AD so do I but different so enjoy adn give me feedback on what you think and which champion i should make a guide on next :)

For runes i take the basic attack speed marks, mana regeneration glyphs and seals, and armor penetration quintessences.

For masteries i take and unusual 23-6-1 build. It works try it :)

start the game with a long sword and a health potion. When i recall i get sword of the occult and berserker greaves. Mid game you want to get a sheen and a zeal, get trinity force as soon as possible. Late game build two infinity edge's and a bloodthirster for life steal

The thing with ezreal is that he has no move that slows enemy's down so you want to finish your enemy quickly. Hes essence flux gives an attack speed buff to any ally that it passes through, this is very useful in team fights. When you engage in a team fight use your arcane shift behind the allied tank open up with trueshot barrage for maximum damage use mystic shot on enemy's that are being targeted and just keep spammimg essence flux. this should get your passive up to 6 stacks which should get you a guaranteed kill.

With your summoner spells Exaust is a must because you have no slow and you can swap flash out for ghost or even teleport.
