Miss Fortune vs Caitlyn

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.

Don't stay in her range for no reason: her autos reach 650, and every few autos, Headshot (passive) hits harder.

Walk around her traps: stepping on a Yordle Snap Trap (W) roots you, reveals you for 3 seconds and gives her a double-range Headshot (passive).

If you can engage, wait for her 90 Caliber Net (E): it's her only way to hop backward, on a 16 to 8 second cooldown.

If a wounded ally is targeted by Ace in the Hole (R), step into the line of fire: any champion on your team can intercept the bullet.
