Ezreal vs Draven

Land Mystic Shot (Q) as often as you can: each hit lowers all your cooldowns and adds a Rising Spell Force (passive) stack.

Detonate Essence Flux (W) with a spell rather than an auto: the orb deals its damage either way, but a spell refunds its mana cost plus a bonus.

Save Arcane Shift (E) to escape unless the kill is certain: it's your only way to reposition, on a 26 to 14 second cooldown.

Cast Trueshot Barrage (R) across the map to finish a fleeing target: it hits everything in its line, but deals less to minions and non-epic monsters.

Play hard when he drops a Spinning Axe (Q): without it, he loses his bonus damage and the Blood Rush (W) reset.

If you have skillshots, aim where his Spinning Axe (Q) falls: he has to go there to catch it.

If you can engage, wait until Stand Aside (E) is used: it's his only spell to push you back, on a 16 to 12 second cooldown.

Don't hand him kills: with League of Draven (passive), each champion he kills gives him bonus gold based on his stored Adoration.

At low health, beware of Whirling Death (R), which crosses the map: it executes a champion below a threshold that grows with his Adoration.
