Earthshaker + Kunkka

Why this works

Picking these two heroes together often means you're doubling down on delayed, area-of-effect stuns, but their kits can be redundant or even conflicting. While an Earthshaker Fissure can theoretically set up Kunkka's Torrent or Ghostship, Kunkka already has X Marks the Spot to do that job more reliably for his own combo. This overlap means you aren't getting as much value as you would by pairing either hero with a different kind of support. Worse, a poorly placed Fissure wall can physically block Kunkka from getting into position for a crucial Tidebringer cleave, actively hurting his damage output.

In practice, this pairing requires a lot of coordination to avoid stepping on each other's toes. In teamfights, one hero's initiation can easily disrupt the other's. Earthshaker might Blink in for an Echo Slam right as Kunkka lands a multi-hero Ghostship, meaning the follow-up stuns don't chain properly because the timings are off. Instead of creating clean lockdown, they often end up acting as two separate initiators fighting for the same moment. The potential for a big play exists, but it's frequently clunky and less reliable than simpler hero combinations.
