Viktor vs Tristana

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.

Don't stay glued to your minions: when her autos kill them, Explosive Charge (E) damages nearby enemies, and her bomb also explodes in an area.

Back off as soon as Explosive Charge (E) is stuck on you: each of her hits makes it stronger, and a bomb that explodes at max stacks resets Rocket Jump (W).

When she activates Rapid Fire (Q) in a fight, back off until the bonus ends, or stun her if you can: her attack speed spikes for the spell's duration.

In teamfights, when Explosive Charge (E) is on you, spread out from your allies: when it explodes, the bomb also damages anyone near you.
