Item #: SCP-XXXX
Object class: Safe
Special Containment Procedures: SCP-XXXX is to be kept in at least two pieces whenever not in testing. SCP-XXXX is not permitted for recreational use without 03 authorization or higher.
Description: SCP-XXXX is a deck of UNO playing cards. when taken apart and examined, SCP-XXXX resembles a normal complete deck, with 25 cards of each color and four "wild" cards.
SCP-XXXX's anomalous effects only manifest if all cards are present in the deck, and the deck has been shuffled within the last twenty-four hours. When a card is drawn from the top of the deck, SCP-XXXX does not seem to decrease in size or mass, regardless of the amount of cards drawn. conversely, when a card is inserted into the deck, size and mass does not increase either. If at least sixteen cards are places face up in a pile, it will also begin to exhibit anomalous properties.
This pile of cards (Henceforth referred to as SCP-XXXX-1), possesses properties similar to that of SCP-XXXX. Placing additional cards in the pile does not seem to cause the mass to increase. However, the shape and size of the pile can fluctuate as cards are added if the pile is disorganized.
After seventy cards have been drawn, SCP-XXXX will only remain active if all cards are being used to play a game. These cards can be used for a game other than UNO, as long as all cards drawn from SCP-XXXX or SCP-XXXX-1 are in use.
