Earthshaker + Omniknight

Why this works

Saving a diving initiator seems like a solid plan. Earthshaker blinks in for an Echo Slam, and Omniknight is right there with Heavenly Grace or Guardian Angel to keep him from getting instantly blown up. This allows Earthshaker to stay in the fight and land more stuns with Aftershock, extending the lockdown from his initial jump. On paper, it's a good way to ensure your big teamfight ultimate gets its full value, turning one hero's suicide mission into a sustained engagement. Omniknight provides the survivability that Earthshaker desperately needs after committing his only escape tool to go in.

In practice, this duo can feel a bit one-dimensional. The entire strategy revolves around Earthshaker finding that perfect jump, and opponents can play around it by spreading out or having instant disables of their own. If the initial Echo Slam is underwhelming, Omniknight is left trying to save a hero who hasn't had much impact. Furthermore, having two melee heroes can create pressure in the laning stage, potentially delaying the critical Blink Dagger timing for Earthshaker. The plan is strong when it works, but it's predictable, which is why it often balances out.
