Miss Fortune vs Ezreal

Fire Double Up (Q) at a dying minion in front of a champion: if the shot kills the minion, the bounce onto the champion always crits.

Switch targets often: Love Tap (passive) adds damage on each new target, and lowers the cooldown of Strut (W).

Activate Strut (W) to get in position before Bullet Time (R): you instantly gain its max move speed bonus, plus attack speed.

Cast Bullet Time (R) on enemies who are CC'd or bunched up in a chokepoint: it's a channeled cone, and each wave can crit.

Stay behind your minions: Mystic Shot (Q) hits the first enemy, and each time it hits you, all his cooldowns go down.

Go all-in when he has used Arcane Shift (E) to move forward: it's his only escape, on a 26 to 14 second cooldown.

Look for head-on teamfights, behind your frontline: Mystic Shot (Q) stops on the first enemy hit, and Essence Flux (W) on the first champion.

At low health, beware of Trueshot Barrage (R) even far from him: the shot crosses the whole map and hits every unit in its line.
