Ezreal

Strengths

Use Arcane Shift to help line up your other skill shots.
You can play Ezreal either as a Attack Damage carry or Ability Power carry depending on how you build him.
You can line up Trueshot Barrage to hit multiple minion waves or even Monsters.

Passive · Rising Spell Force — Ezreal gains increasing Attack Speed each time he successfully hits a spell, stacking up to 5 times.
Q · Mystic Shot — Ezreal fires a damaging bolt of energy which reduces all of his cooldowns slightly if it strikes an enemy unit.
W · Essence Flux — Ezreal fires an orb that sticks to the first champion or objective hit. If Ezreal hits an enemy with the orb, it detonates and deals damage.
E · Arcane Shift — Ezreal teleports to a target nearby location and fires a homing bolt which strikes the nearest enemy unit. Prioritizes enemies stuck with Essence Flux.
Ultimate · Trueshot Barrage — Ezreal winds up before firing a powerful barrage of energy that deals massive damage to each unit it passes through (damage is reduced for minions and non-epic monsters).

A suggested 5-lane lineup built around Ezreal, based on hero partnerships and role synergy — not win rate.
