These replacement decks for the Anniversary Waltz will give you the opportunity to do the trick 40 times... (there are some cards that are same both sides and two that have a blank back ... )

Rumor are flying that USPlaying Card Co may be discontinuing the manufacture of this product. In case that is what is happening, I stocked in a few extra decks.

I hope that things work out and they continue making them. It would be a real shame if this source dried up.
