Dirge

Dirge is an uncommon Necrobinder skill costing 0 Energy that Summons 3 X times and adds X Souls into your Draw Pile, where X scales with some game state. This dual-purpose card bridges the Osty/Summon and Souls archetypes, providing both Osty HP growth and Soul generation in a single free play.

Dirge feeds Devour Life's Soul-to-Summon conversion for compounding Summoning value, and Haunt triggers on the Souls generated. Soul Storm's Exhaust Pile counter grows as those Souls are played and Exhausted. The Summon portion synergizes with Calcify and Necro Mastery for Osty-based strategies.

In the Necrobinder Osty/Summon archetype with Souls support, Dirge is the ultimate bridge card. Against any boss, the free cost means it never competes for Energy with your main plays. Against multi-phase fights like Test Subject #C10 and Doormaker, the combined Summon and Soul generation keeps both your Osty and Souls engines fueled simultaneously.
