Faceless Void + Tinker

Why this works

Landing a big Chronosphere often sets up a clean kill, but Tinker's damage doesn't always align with it. His contribution comes in repeated bursts from a safe distance, which is great for long fights or picking off stragglers. Inside a Chronosphere, however, the goal is to delete a target instantly. Faceless Void needs immediate, high-impact spells from his team to make that happen. While Tinker can throw out Laser and missiles, his full damage cycle with Rearm takes time, and he has to be positioned perfectly to even participate, which is rare for a hero who typically plays far from the main fight.

The game plan for these two heroes tends to pull in opposite directions. Tinker excels at applying map-wide pressure by pushing lanes, forcing reactions, and farming aggressively. This frequently means he's not grouped with the team when an opportunity for a Chronosphere pickoff arises. Faceless Void relies on his team being ready to follow up on his ultimate to create tempo and take objectives. If Tinker is on the other side of the map, that's one less hero contributing damage inside the dome. While a coordinated team might make it work in the late game, their mid-game timings rarely sync up.
