Good little review there Rob - do you thinm you will ever use these cards in routines or anything?
If I remember correctly I managed to find a few decks of these on the net somewhere, quite a while ago - as I recall I purchased a brick of coloured cards - I got a tiger deck, ghost deck, green deck, blue deck, pink deck, a black backed normal deck of bikes, an orange backed deck of bikes and a normal red and blue deck.
I agree with you're says though - tricks are quite difficult with these, and (as I have found with tiger decks) people actually get confused as to what card they have because the pips are white on a green background as opposed to red / black - plus people do get VERY suspicious of the cards
I would say one thing though - for colour changes and card force tricks these cards are a godsend - they add such a bigger impact than 'oh look, here is your card' as it becomes - 'wow my card is a totally different colour on the back *turn over* AND ON THE FACE !!!'
Uses for these cards: (well, how I used them)
Pink: In clubs / bars use these on the 'playboy bunny' generation of girls who you see hanging round - at university on campus bars and clubs these kind of girls were everywhere and the first reaction was 'wow PINK CARDS WOOOOO!!!'
Green: I had mine whilst the whole 'wow its St Patricks day lets get drunk' thing was going on - these went down a treat (much ion the same way the pink ones did - 'WOW! GREEN CARDS')
Blue faced / random coloured back decks: Colour change routines / card revelations which involve a force of any kind
Ghost / Tiger: In clubs with UV lights, as these light up a treat (I prefer ghost deck, as in a dimly lit club they look much less suspicious, and hence I find you get less of 'they must be a trick deck'
Final thing (sorry to be stealing this thread Rob

)
I got purchased a very strange deck of cards...An Elephant deck...They are camo green (much like Robs green cards, but a camo / olive green) and they have black pips...the ace however, is an elephant...:S - anyone got a clue where these are from / why they were made?
