Miss Fortune vs Kalista

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.

After a trade, back off until her spears fall out: they stay stuck for 4 seconds, and Rend (E) deals more damage for each extra spear.

Cast your spells as she starts an auto: she can't cancel the animation, and Martial Poise (passive) only makes her hop once the shot is out.

Focus her Oathsworn when you can: without them, Fate's Call (R) has no one to throw, and Sentinel (W) loses its bonus damage.

When Fate's Call (R) pulls in her Oathsworn, spread out: they can launch within 4 seconds, stop at the first champion hit and knock back nearby enemies.
