Faceless Void + Shadow Fiend

Why this works

Setting up a teamfight around Chronosphere can be awkward for this pairing. The main issue is that Faceless Void's ultimate freezes allies inside it, completely preventing Shadow Fiend from casting Requiem of Souls or Shadowraze if he gets caught. This forces Shadow Fiend to play perfectly on the edge of the Chronosphere, where he is vulnerable to being targeted by enemies outside the bubble. While both heroes bring a lot of physical damage to a fight, their signature abilities simply don't have a natural way to combine their effects, often working against each other in the most critical moments.

This lack of synergy means fights are often less clean than either hero would prefer. Instead of a clear setup, the team has to manage two separate, powerful ultimates that require very different positioning. Faceless Void wants to trap key targets, while Shadow Fiend needs space to either channel or land his razes safely. Because both heroes also demand significant farm to hit their item timings, sharing the map can feel inefficient. The lineup can feel greedy and vulnerable during the mid-game, relying on one hero to create space while the other farms, without a strong guarantee of a powerful late-game teamfight combination.
