I use this forcing decks in three ways. One is for packet tricks - extra cards can be useful for constructing sets of packet tricks to sell or give to friends. Two is signed cards - you'll destroy less decks. Three is for forcing. I bought this deck to perform Tommy Wonder's Tamed Cards Routine. Essentially a version of Wild Card. Using the Force deck and putting it away adds level of convincing that a randomly selected card can be printed at will.

Great for forces but also really good for making gaffed cards with (especially Torn and Rrestored effects) or just using as duplicate cards in effects. You can also make you're own svengali decks using a one way force deck if you want to.

I would recommend getting at least one of these decks to put in your magic box because I find they always come in handy.
