Bullshit Shuffle

Exploration Stage: Red Rose Cafe
From: Alex
Description: Even the mafia doesn't cheat when it comes to gambling. Otherwise, fortune would be forever away from you. But Master F. doesn't seem to be afraid of anything. Don't worry. We'll definitely catch him! He must have had a pair of playing cards with the wrong cards in them. Can you help me find them?
Completed: Excellent! Scammers use this a lot. They use it to put the removed card back together with the fake card. With this kind of evidence, they can take Master F to court!
