Item #: SCP-6000
Object Class: Euclid
Special Containment Procedures: SCP-6000 is to be contained in a storage cabinet within Site (██). There is to be no interaction with SCP-6000 unless for testing, in which only personnel level 3 or higher may execute.
Description: SCP-6000 appears to be a Uno deck with a smidge of blood on every plus four card. When the game is played with the plus four cards taken out the game plays normally, but when a plus four card is used, the subject who receives it will be transported to another dimension only to appear back in fifteen minutes. When the person comes back the game continues with the person who was initially transported losing the game. No matter what the subject who comes back will always lose, even when cheating. After the game is done the subject who won and the subject who lost will disappear, after two hours the person who won come back as another Uno deck with further analysis proving that the deck is made of human tissue, bone, and blood while the subject who lost comes back as a deformed creature that repeats the phrase “I lost” over and over until it dies presumably of starvation.
Addendum 1: Interaction with the creature that lost is not advised since the creature is extremely hostile with endurance that is capable of sustained gunfire and anti-matter rifle shots. The only real way to stop the creature is to present the Uno deck a few feet away from it. After the deck is a few feet away from the creature it will become docile and continues the phrase “I lost”. Dissection of the creature show nothing, not even organs. All personal are advised to not interact with the deck or the creature when in testing in order to avoid a repeat of the incident that happened when Dr. (████) was testing the creature and it led to a subsequent containment breach of both the creature and other Euclid level class items as well.
