Shadow Fiend + Phantom Lancer

Why this works

Picking these two cores together is a bet on overwhelming the enemy with pure damage output. Shadow Fiend brings heavy area-of-effect magic from his Shadowrazes and Requiem of Souls, which can soften up an entire team at once. This creates an ideal scenario for Phantom Lancer to find an isolated target and quickly build up an army of illusions. The core problem is that they're both glass cannons. Neither hero offers the reliable stuns or lockdown that the other needs to apply their damage safely. They are entirely reliant on their supports to provide initiation and control, making the draft feel incomplete on its own.

The game plan is to have both heroes hit their timings and force fights around objectives. When it works, Shadow Fiend's ultimate creates enough chaos for Phantom Lancer to safely commit and run down scattered enemies. When it fails, their shared lack of defensive tools or lockdown becomes a critical weakness. Enemies can easily split them up, kite them, and prevent them from ever getting their full damage off. The success of this pairing often depends on whether they can secure an early lead and maintain momentum, as they have few tools to mount a comeback from a deficit.
