December's issue of Genii magazine has a free DVD with Simon Lovell explaining his Ambitious Card routine.
It's good - especially as a free give away.
There are also "hidden" extras on the DVD which later issues of Genii will explain how to get to.
However if you run it on a PC you can just access the files directly.
Our local magic shop closed down just a few days ago, so now I have no outlet to find the magizine at and I really don't want to go with a subscription...
