Why Viktor is favored
Viktor can use Chaos Storm (R)'s initial cast to interrupt Nether Grasp (R), and Hextech Ray (E) can clear Malzahar's Voidlings while also pressuring him. That undercuts Malzahar's usual suppression and wave-push patterns, giving Viktor the advantage in higher-ranked games.
Measured in High Elo: Viktor wins 2.6pp more often than expected over 1,282 games.
How to play as Viktor
Use Hextech Ray (E) through Malzahar and his Voidlings to answer his push. If he steps forward for Nether Grasp (R), cast Chaos Storm (R) as the channel begins to interrupt it; watch for his jungler before walking up.
Chaos Storm (R) interrupts channels on its initial cast, so it can stop Malzahar's Nether Grasp (R) if Viktor's cast hits as the suppression begins.
Hextech Ray (E) can hit Malzahar and his Voidlings together, removing the minions that drive his early push while still dealing lane damage.
How to play as Malzahar
Keep Void Shift (P) available and use Void Swarm (W) to maintain wave pressure, but avoid starting Nether Grasp (R) while Viktor's Chaos Storm (R) is ready to interrupt the channel. Look for the gank when Viktor has spent R or is low enough to suppress safely.
