What is the Christmas song where there is a deck of cards in a hallway full of doors?

The Christmas song you’re referring to is "The Twelve Days of Christmas." In this song, the mention of a deck of cards is likely a playful interpretation of the various gifts listed, which includes "twelve drummers drumming" and other items. The imagery of a hallway full of doors may evoke the idea of the many gifts being presented, each behind a different door, reminiscent of an advent calendar. However, the specific mention of a deck of cards is not a standard part of the traditional lyrics.
