Raritylegendary
TextAs an action, you can throw this card to an unoccupied space on the ground within 60 feet of yourself while speaking a command word, whereupon the card magically transforms into a deck defender (see chapter 9 for its stat block) for up to 1 minute or until you use an action to speak the command word again, whereupon it transforms back into a card. The deck defender obeys your spoken commands. If you issue no commands, it takes the Dodge action and moves to avoid danger. The deck defender reverts to a card early if it drops to 0 hit points. Once this property is used, it can't be used again until the next dawn. Source: The Book of Many Things p. 14
