Nami vs Rakan

Cast Aqua Prison (Q) on a slowed or immobile target, or where they're heading: the bubble lands in an area and stuns every enemy on impact.

Cast Tidecaller's Blessing (E) on your ADC just before they trade: their next autos and abilities slow and deal bonus magic damage.

Cast Ebb and Flow (W) so it bounces from one champion to another: it heals each ally, damages each enemy, and only hits the same champion once.

Cast Tidal Wave (R) to engage or to break an enemy engage: enemies hit take a knock-up and a slow, which lasts longer on those farther away.

Stay behind your minions: Gleaming Quill (Q) strikes the first enemy in its path, and if it hits a champion, Rakan heals his team.

Keep your distance when his ADC steps up: Grand Entrance (W) lets him leap onto you, and enemies around his landing spot take a knock-up.

If you have CC, save it for when he lands in the middle of your team: only Battle Dance (E) then lets him leave toward an ally.

Spread out from your allies when he casts The Quickness (R): he charms every enemy he touches while running.
