It's like stealing because you owed him the cards. They should be his property. You chose to keep his property, as well as the profit from the sale of his property.
And to add to this...
Michigan Legislature - Section 750.356
750.356 Larceny; property; penalties; total value of property stolen; enhanced sentence; prior convictions; "nonferrous metal" defined.
(1) A person who commits larceny by stealing any of the following property of another person is guilty of a crime as provided in this section:
(a) Money, goods
, or chattels.
(5) If the property stolen has a value of less than $200.00, the person is guilty of a misdemeanor punishable by imprisonment for not more than 93 days or a fine of not more than $500.00 or 3 times the value of the property stolen, whichever is greater, or both imprisonment and a fine.
