Hi, I am doing this guide as part of an English portfolio and to help new players and even old players find new and exciting ways to play Ezreal. Ezreal is a harder champ to master compared to others due to his skill's being skill shots. Please note that this is the first time that I have made a guide. I don't know how to add in pictures or use many of the other features on here, but I hope you enjoy the guide and find it helpful.

Pros

Great Range
Good finisher/opener
Free flash with arcane shift
Good burst damage early game
Awesome harass

Cons

He is fragile
He has no crowd control
He is vulnerable to CC
Needs lots of Mana

Greater seal of Crit Damage
- This allows for better critical hits which is good because Ez's attacks are physical

Greater Mark of Attack Damage
-This is good because Ez in this guide will be going as an AD carry

Greater Glyph of CD Reduction
-This is useful because Ez is very reliant on his Skills

Greater Quintessence of Armor
- This is useful because Ez is squishy and needs the extra armor to help in team fights

For a AD carry Ezreal attack damage masteries are very useful, so many of the masteries in the offense section are useful for Ezreal and can be chosen as shown.

For Ezreal a few masteries in Utility will be helpful in the long run because of the cool down reduction and the increased movement.

Flash
- I like to use flash although Ez already has one it can be very helpful in setting up a skill shot or getting out of a bad situation

Exhaust
- I like this spell because it makes it easier to chase opponents and gives the upper hand in 1v1s

Start off with the standard boots and 3 pots. This will give you better movement and ensure that you won't have to go back too soon.
Next get the doran's blade for added damage and life steal.
Finish your boots by getting the Berserkers for added attack speed to help farm better. Then I recommend getting the B.F. Sword for attack damage and turn that into an IE later.
Build towards the Tri-Force for better farming and on hit effects. This will allow you to farm better allowing you to get a Phage for more health and a slow to chase down opponents. Turn the Phage into a Frozen mallet for more health and slowing effects. To help against other attack damage champions get a guardian Angel for the armor and the added effect of a revive after being killed. Note that this effect has a long cool down, so don't rely too heavily on this effect. To finish off your items get a Last Whisperer for the armor penetration. This makes Ezreal scary and will destroy most tanks.

R>Q>E>W
Open with your Q to allow for better farming and harass early in the game. It also reduces the cool down of skills if the attack hits an enemy.
Get your E after your initial Q to allow for use of the flash to help juke opponents and to set up better skill shot opportunities.
Next get your E for the utility as it helps team mates heal better and reduces enemy healing when hit with the W.
Get you Ult at lvl 6 as always.
Then follow the skill sequence knowing that the Ult always has first priority, then comes the Q, then the E, then your W.

Team Fights - For Ezreal be careful in team fights because he tends to be focused due to his low health. Stay at the edge of the battle and focus their carry.

Farming - Ezreal is fairly good at farming and is an auto attacking beast. Make sure to last hit minions to get the gold. Judge the damage output by seeing how much the health bars on the minions goes down for every attack, then wait for the minion's health to get in the range that would allow for the attack to kill the minion.

Laneing - Try to get a good support champion like Soraka, so you can get the heals and mana boosts.
