Magic Tricks

I purchased two Brainwave decks very recently from Penguin and was most impressed with the their delivery to Australia.
However both decks work well with the rough & smooth but will
not spread at the correct named card. I have performed the
Brainwave deck for very many years successfully but in recent months when purchasing new Brainwave decks, they all fail to spread at the appropriate place. The decks I have been buying are all from Murphy's Magic, so I think the fault lies with them and not Penguin Magic. The Brainwave routine has long been my favourite effect, so feeling disappointed that the
Murphy's Decks ( that most dealers now supply) are poorly prepared by the manufacturer. David J. (down under)
