I perform great magic with any deck of cards.
I do not need to spend extreme amounts of money on a pack of cards which will wear out anyway just the same as my normal deck.
On the other hand, if the deck was used by someone famous, or signed or any marking of a use of a famous magician. That is what would make the deck worth keeping in my eyes.
Limited edition does not bother me, unless I collected all the deck of cards, but that would sort of be a waste of money, as I am a magician and not a collector.
