Doom + Grimstroke

Why this works

Landing Soulbind on two heroes seems like the perfect setup for a double ultimate, but the execution is often awkward. Grimstroke can apply his ultimate from a relatively safe distance, but for the follow-up, Doom has to get much closer to cast his own. This forces Doom to burn a Blink Dagger or simply run into the enemy team, exposing himself to be focused and controlled before he can even get his spell off. It's a heavy commitment from both heroes, and using two of the game's longest cooldowns for a play that can be foiled by a single save or some careful positioning feels inefficient.

As a result, the game plan can become very predictable. Good opponents will see the draft and instinctively play more spread out, denying Grimstroke the setup he needs. This leaves your team trying to force a specific, telegraphed fight over and over. When the big combo does land, it can secure an important kill, but the investment is huge. When it fails because the targets split or a BKB is used, you're left with nothing for the next teamfight. The outcome of the game can hinge on these high-stakes plays, making the whole pairing feel inconsistent.
