Doom + Razor

Why this works

Drafting both Doom and Razor often means you're committing to neutralizing one specific enemy. Both heroes are specialists at this. Doom uses his ultimate to make a single target completely ineffective by disabling their spells and items. Razor accomplishes something similar with Static Link, draining away a hero's damage output until they're no longer a threat. The core issue is that these two signature abilities don't stack well. Using both on the same target is redundant; that hero is already out of the fight from one spell, making the second one feel wasted.

This forces a tough decision in teamfights. You can either use both spells on one enemy for an absolutely guaranteed kill, leaving the rest of their team free to respond, or you can try to have Doom and Razor focus different targets. Splitting focus can work, but the heroes don't offer much to set each other up. There's no reliable stun to hold someone for a Static Link, nor does Razor help Doom get into position. The lineup ends up with two powerful single-target effects but can lack the broader control or burst needed to win a chaotic five-on-five engagement.
