Corki vs Aphelios

Poke with Phosphorus Bomb (Q): the area and the champions hit are revealed for a few seconds, enough to follow an opponent into a brush.

Start your trades with Gatling Gun (E): it lowers the armor and magic resist of the enemies hit while it fires.

Save the Big One, every third missile of Missile Barrage (R), for a champion: it deals much more damage than the other missiles.

Save Valkyrie (W) to escape rather than to engage: without it, you're vulnerable for its 20 to 12 second cooldown.

Only engage with Special Delivery if your team can follow: after using it, as after Valkyrie (W), you're vulnerable.

Back off when he holds Gravitum and has slowed you: Weapon Abilities (Q) with the cannon roots every enemy that weapon has slowed.

If you can engage, go for him when his support drifts away: his kit has no dash, and only Severum makes him run faster.

Spread out from your allies when he has Moonlight Vigil (R): the blast explodes on the first champion hit, damages those nearby, then he attacks each of them.

When he deploys the Crescendum sentry with Weapon Abilities (Q), leave its area: it attacks you with his off-hand weapon.
