Clockwerk + Slark

Why this works

Setting up a gank for Slark often starts well. Clockwerk can land a long-range Hookshot to lock a target down, which is exactly the kind of initiation Slark loves. The problem comes with the follow-up. Clockwerk's Power Cogs are meant to trap the enemy in place with him, but they also create a physical barrier. As a melee hero, Slark is stuck outside, unable to connect his attacks and build up Essence Shift stacks. He's forced to use Pounce to jump over the cogs, spending a key mobility spell just to join a fight that was supposedly set up for him.

This clunky interaction defines their partnership. A successful gank requires a lot of coordination, like having Slark already in position before the Cogs come up, or the Clockwerk trying to knock the target out towards him. More often, the delay gives the enemy time to react, or forces Slark to commit Pounce early, leaving him without an escape. While the global vision from Rocket Flare helps Slark find isolated targets later in the game, the core fighting synergy is awkward. Slark simply works better with heroes who can hold someone down without putting a fence between them.
