Bard vs Rakan

Line up Cosmic Binding (Q) with a wall or a second enemy behind your target: the missile then stuns every enemy hit.

Cast Tempered Fate (R) to freeze a teamfight, or a tower during a dive: everything hit, allies included, goes into stasis.

Open Magical Journey (E) to roam or to get your team out: the portal crosses nearby terrain, but enemies can use it too.

Collect the Traveler's Call (passive) Chimes whenever your lane allows: they give XP and mana, and enough Chimes add area damage and a slow to your Meeps.

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.
