Wound
Wound is a status card added to your deck by several enemies and relics, including the Gremlin Nob and the Writhing Mass. It is permanently Unplayable and has no effect when drawn — it simply occupies a hand slot, reducing the number of useful cards you can play each turn. Wound cannot be exhausted, played, or discarded voluntarily, so the only way to deal with it is to cycle through your deck and hope it shows up in turns where you have otherwise-full hands. Avoid sources of Wound when possible.
