Carver's Meat Packing and Storage

Unique location. After a vampire with capacity 3 or less goes to torpor, put 1 hostage counter on them. Vampires with any hostage counters cannot be moved to the ready region or be diablerized. Lock during your master phase to add X blood to a ready vampire you control, where X is the number of vampires with any hostage counters. During any unlock phase, any ready vampire can burn 2 blood to burn any vampire's hostage counters. After this card leaves play, burn all the hostage counters.
