I have bought decks of all the colors available in order to do various color-change / multicolor
packet tricks such as Double Chameleon, Spin Doctor, Restless Colors, etc.
I used three
jacks from this gold deck along with a queen and a joker from the silver deck to do "Montinator". I
also used one of the aces from this gold deck for "Spin Doctor" along with aces from the silver
deck, a blue deck, and a red deck.
I noticed that with regular handling just from
practicing, the gold back of the ace was starting to turn greenish on the sides. The cards from the
other decks showed no wear at all.
So I swapped it out for a different ace. It didn't take
long before I noticed that yet again the area on the back where you put pressure on the card to push
off was losing the gold color and turning greenish. The aces from the other color decks are still
perfectly fine.
Ditto for the gold deck jacks from the Montinator packet. The cards from
the silver deck are like new, and they get handled more in the Montinator trick than the three gold
cards. But even with less handling, the three cards from the gold deck are starting to turn
greenish on the backs.
The ink from the gold deck simply doesn't hold up well to the kind
of handling involved in packet tricks (multiple pushoffs, Elmsley counts, etc).
So... I
would NOT recommend this particular color for packet tricks. They look great, but they don't last.
