Neurosurge

Neurosurge is a rare Necrobinder power costing 0 Energy that immediately grants 3 Energy and draws 2 cards, but applies 3 Doom to yourself at the start of each subsequent turn. This powerful resource burst comes with a ticking clock, creating urgency to close out fights before self-inflicted Doom becomes lethal.

Neurosurge enables explosive turns with End of Days, which costs 3 Energy, or Reaper Form at the same cost. Borrowed Time adds even more self-Doom for Energy, while Death's Door provides Block that scales with Doom application to offset the self-damage risk.

In the Necrobinder Doom archetype, Neurosurge is a high-risk accelerator that demands you end fights quickly. Against bosses you can burst down like Kin Priest and Vantom, the 3-Energy injection is transformative. Against longer fights like Kaiser Crab, the accumulating self-Doom becomes dangerous. Pair with defensive tools like Shroud and Death's Door to buy time while the Doom engine closes out the fight.
