Viktor vs Draven

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.

Play hard when he drops a Spinning Axe (Q): without it, he loses his bonus damage and the Blood Rush (W) reset.

If you have skillshots, aim where his Spinning Axe (Q) falls: he has to go there to catch it.

If you can engage, wait until Stand Aside (E) is used: it's his only spell to push you back, on a 16 to 12 second cooldown.

Don't hand him kills: with League of Draven (passive), each champion he kills gives him bonus gold based on his stored Adoration.

At low health, beware of Whirling Death (R), which crosses the map: it executes a champion below a threshold that grows with his Adoration.
