Slark + Ursa

Why this works

Stacking up single-target physical damage from Ursa and Slark on the same team often leads to diminishing returns. Both heroes need to land consecutive hits on a single enemy to be effective—Ursa to build Fury Swipes stacks and Slark for Essence Shift. When they focus the same target, they're competing for attack uptime rather than truly enabling each other. Usually, the damage from one is sufficient for a kill, so adding the second doesn't significantly speed up the process. This redundancy means the team isn't getting a different type of threat, like magic burst or control, from that second core position.

This shared role creates pressure on the team's overall game plan. Having both Ursa and Slark means the lineup can be starved for resources, as both heroes have similar farming patterns and item timings. It also makes the team's strategy predictable: run at a single hero. An enemy team can counter this by grouping up, buying Ghost Scepters, or focusing on kiting abilities. While both heroes are strong duelists, putting them together doesn't cover their shared weakness to being controlled and burst down, and it can leave the team lacking in broader teamfight utility or magical damage.
