Earthshaker + Razor

Why this works

Seeing a long Fissure stun might make you think it’s the perfect setup for Static Link, but the reality is more complicated. Any hero with damage appreciates that kind of lockdown, so the benefit isn't unique to Razor. Their goals in a fight can also diverge. Earthshaker wants to use his spells to control as many enemies as possible, hitting a big Echo Slam or blocking off paths. Meanwhile, Razor is entirely focused on draining a single, high-priority target with his link. They often end up working in parallel on separate problems rather than combining their efforts on one.

This disconnect plays out across the game. A Fissure into Static Link combo in lane is too mana-intensive for Earthshaker to do consistently. In mid-game teamfights, a good Blink Dagger initiation from Earthshaker can certainly create space for Razor to use Eye of the Storm, but it's not a dependent relationship. If Razor finds a good link on his own, he doesn't really need a follow-up stun to finish the job. Ultimately, neither hero fundamentally changes how the other one needs to play; they function as two powerful heroes who happen to be on the same team.
