Funerary Mask

Funerary Mask is a Necrobinder-only relic that automatically adds 3 Soul cards to the draw pile at the start of combat. Soul cards are Necrobinder's core resource — playing them grants a variety of summoning and buff effects. Because every fight starts with a guaranteed Soul supply, the engine spins up reliably.

Soul cards are 0 cost and can be used to buff minions or trigger extra summons. With 3 added to the draw pile, you're more likely to draw Souls early, smoothing Osti deployment and upgrades. Necrobinder's minion strategy collapses when Souls run dry, so a stable source matters enormously.

The weakness is that Soul cards go into the draw pile, so they may take a few turns to come up. Compared to Big Hat (which adds directly to hand) it's slower, but as the deck cycles, Souls keep appearing — the mid-combat consistency is high.
