When you've got company over and are looking for a fun activity, playing a card game is often a fun idea. But sometimes you don't have a full deck in your posession. And you don't feel like buying one either.
This Redditor pointed out that issue out further. When flipped over, the circled cards should be facing the opposite directon. But they don't, which seems to indicate that these are not the same cards.
From there, things got pretty heated as Reddit attempted to expose a possible liar. But Eraaaaaan had an explanation. The image posted to Reddit was actually from a poster he made of the cards, which involved having the cards reprinted.
Eraaaaaan continued, saying that he used the reprint files for the poster, but some of those reprints were backwards. So on the poster, there are things that make is a bit suspect. But he insists that it's real.
He also posted this photo of all the cards, face up. In this case, all the cards really are there. Although we don't get to see the backs of the cards at the same time to prove that they're from different decks.
However, the OP still managed to provide enough evidence to convince the rest of Reddit. His original post may have included a bad representation of the project, but he really did it. He collected a full deck made up of random cards.
Eraaaaaan also said he had restrictions for his pickup, saying, "The rule I had when finding more than one card from the same deck at one location: I am only allowed to pick ONE of the cards, and I'm not allowed to flip any card over or touch it before picking it up, like a Mikado game. So if, for example, I would find an entire deck on the street - I am NOT allowed to rummage through it and select the one card I need."
