During their poker game at the Borscht Bowl Club, Smith tasked Olga Orly with planting a fifth ace in Wright's hand that would be discovered during a body search. Smith's intent with this scheme was to cause Wright to lose the game and tarnish his reputation of "never losing a game in 7 years", by making it seem that he was a cheater. However, Wright quickly found and disposed of the card, causing Smith to knock Orly out with a grape juice bottle in a fit of anger.
After leaving the room for a while, Wright returned to find Smith dead. After calling the police, Wright called Kristoph Gavin, who made a curious statement about "someone crack[ing] that flawless bone china pate," referring to Smith's baldness; Gavin should have been unaware of Smith bald head, since the victim always wore a hat. His suspicion raised, Wright put some blood on another one of the aces
Phoenix Wright gave the card to his daughter, Trucy Wright, who subsequent gave it to Apollo Justice during Phoenix's trial for Smith's murder. When Justice presented it in court to explain why the killer took the fifth ace from the scene and suggested the blood fell from Smith's head, Gavin declared it to be a fake, but Phoenix pointed out that only the real killer would be able to identify it as such. This led to a small string of deductions which revealed that first, the victim had been facing the other way in order for blood to fall on the card; second, the killer would have had to be in the area where a cupboard was, otherwise they wouldn't have been able to hit him from the front; third, the cupboard would've had to be right next to the window, preventing Gavin from seeing in that way like he claimed, and lastly, the killer had to have been in the secret passage behind said cupboard in order to ambush Smith. Although this helped successfully incriminate Gavin for Smith's murder and clear Phoenix's name, the fact that he had given Justice falsified evidence shocked the rookie lawyer, causing him to punch the former defense attorney in anger.
