Pudge + Slark

Why this works

Pairing these two heroes commits the draft heavily to a single-target ganking plan. Pudge provides a long-range initiation with Meat Hook, setting up a target for Slark to Pounce and build Essence Shift stacks on. The main issue is that both heroes are already designed to isolate and kill lone enemies. Slark is slippery enough to find his own targets, and Dismember offers lockdown for a hero who already has a leash. This means they are overlapping in their roles rather than complementing each other's weaknesses, forcing the rest of the team to provide things like wave clear and teamfight control.

This one-dimensional approach often hinges on the early and mid-game. If the pickoffs are successful and frequent, you can snowball the map. However, the strategy falls apart if the enemy team simply groups up. A five-man push is difficult for either Pudge or Slark to deal with, as they excel at skirmishes, not full-scale engagements. Your game plan becomes predictable, and opponents can counter it with good defensive vision and by staying together, which makes finding the necessary single-target kills much harder.
