Call of the Void

Call of the Void is a rare Necrobinder power costing 1 Energy that adds 1 random card to your Hand at the start of each turn, with the Ethereal keyword added to it. This provides perpetual card advantage and feeds Ethereal-matters synergies, though the random nature means the value varies from turn to turn.

Call of the Void generates Ethereal cards that trigger Spirit of Ash for Block, Pagestorm for extra draws, and fuel Pull from Below's damage scaling. Banshee's Cry costs less for each Ethereal card played, and the random cards may occasionally provide exactly the tool needed for a given situation.

In the Necrobinder Souls archetype, Call of the Void provides consistent card flow and Ethereal triggers. Against long-duration bosses like Kaiser Crab and Doormaker, the cumulative value of a free card every turn generates significant advantage. Even in Doom and Osty/Summon builds, the extra card and Ethereal synergy make Call of the Void a strong utility pick.
