Ursa + Void Spirit

Why this works

Drafting both these heroes can create a mid-game identity crisis. Ursa and Void Spirit are both aggressive cores who want to hit their timings and take over the map, but their kits don't help each other accomplish that goal. Ursa needs to stick to a single target to build up Fury Swipes damage, which means he relies on long-duration lockdown. Void Spirit offers a brief pull with Aether Remnant and a lot of mobile burst damage, but he doesn't provide the hard control or setup that lets Ursa stay on top of a key enemy. They end up fighting near each other, but not truly with each other.

This lack of synergy becomes obvious during ganks and teamfights. Void Spirit can initiate from a long distance, but Ursa is often too slow to connect before the target recovers or repositions. The enemy team can kite the Ursa while dealing with Void Spirit’s spell damage, effectively splitting the fight. To make the combination work, your team has to find all of its control and teamfight setup from the other three positions, which can be a huge drafting challenge. Without it, both heroes are left to fend for themselves, which gets much harder once opponents start grouping up.
