Miss Fortune vs Samira

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.

Take a trade once Wild Rush (E) is used: it's her only dash, and it only comes back if a champion she damaged dies within 3 seconds.

If you have projectiles, wait for Blade Whirl (W) to end: it destroys those that enter its area, but not spells without a projectile.

Back off when she chains her hits: each one that differs from the last builds her Style, and at an S rating, Inferno Trigger (R) shoots every enemy around her.
