Clockwerk + Viper

Why this works

Getting caught by a long-range Hookshot is a death sentence in theory. You're trapped inside Power Cogs, isolated and helpless, while Viper unloads Nethertoxin and his corrosive poisons. This setup can feel oppressive, as it focuses all the kill pressure onto a single hero. The core idea is sound: Clockwerk provides the hard initiation and lockdown, and Viper provides the sustained damage and debilitating slows to finish the job. Both heroes excel at making one target's life miserable for an extended period.

The problem is that their kits have a lot of overlap without covering each other's weaknesses. Viper is already great at locking a single hero down with Viper Strike, so Clockwerk's Cogs can feel redundant compared to a support with stuns or saves. In teamfights, their ideal positioning clashes. Clockwerk wants to dive the backline, but Viper needs to stay on the edge of the fight. This often leaves Clockwerk isolated after his initiation or forces him to play a less effective peeling role for a Viper who can already kite well on his own. The combo relies on finding solo pickoffs, because in a full five-on-five, the lack of area damage or team sustain becomes obvious.
