Three missing earlier 1st and 2nd issue cards were discovered from the Mohegan Sun at Pocono Downs. Newly added cards are CG135262, CG135263 & CG135264. There are a number of variations of the earlier cards from Pocono Downs and it's unclear what order they were actually used. They've been grouped based on the reverse text/design to best describe the cards so at least they are documented. The Mohegan Sun at Pocono Downs now uses the Momentum style cards similar to those used at the Mohegan Sun casino in CT, with all four levels now used in PA - Core (1), Leap (2), Ascend (3) and Soar (4).
