Viktor vs Smolder

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.

Take your trades early: his basic spells only gain damage with the Dragon Practice (passive) stacks he builds over the game.

If you have hard CC, save it for Flap, Flap, Flap (E): it's his only way to escape, and hard CC interrupts his flight.

Don't stay grouped with your allies against him: empowered, Super Scorcher Breath (Q) also damages around its target and behind it.

Get out of the center of MMOOOMMMM! (R): that's where the breath hits hardest and slows.
