Viktor vs Lucian

Poke with Hextech Ray (E), fired in the direction you choose: it hits every enemy in its line, and its upgrade adds an aftershock in its wake.

After Siphon Power (Q), land an auto within 4 seconds: it deals bonus magic damage, and the spell's shield covers you during the trade.

Place Gravity Field (W) in your target's path, then fire Hextech Ray (E): the field slows them, and if they stay in it for 1.25 seconds, they're stunned.

Glorious Evolution (passive) upgrades a spell every 100 Hex Fragments: Hextech Ray (E) to poke and clear, Siphon Power (Q) to survive, Gravity Field (W) to slow.

Place Arcane Storm (R) on grouped enemies: it follows the champions it just damaged on its own, and you can recast it to move it.

Punish him after an aggressive dash: Relentless Pursuit (E) has a 16 to 14 second cooldown, only reduced when his double shots hit.

Back off after each of his spells: Lightslinger (passive) doubles the next auto, so his damage comes in short bursts.

If your attack range beats his 500 units, poke him from outside it: he then has to use Relentless Pursuit (E) to get back on you.

If you survive the laning phase, play for time: Lucian is strongest early and loses impact once everyone has their items.
