Big Hat

Big Hat is a Necrobinder-only relic that adds 2 random Ethereal cards to your hand at combat start. Ethereal cards disappear after play, but many carry powerful effects. Each combat hands you 2 free resource cards.

Ethereal cards include attacks, defends, summon helpers, and more, enabling flexible responses to any situation. There is randomness, but nearly every Ethereal card is 0-cost or low-cost, so misses are rare. Opening hand becomes effectively 7 cards, hugely improving turn-1 tempo.

Paired with Death Mask, every combat auto-adds 2 Ethereal cards and 3 Soul cards, making Necrobinder's resources rock-solid. Necrobinder also has low max HP, so Ethereal early defense and damage preserving HP is a key benefit.
