Hmmm....several points to make so let me get started

Please don't take them the wrong way, I'm not trying to be harsh.
If you don't know what a swing cut is you are probably just starting in magic. If that is so I would leave off purchasing 'ready-made' tricks like Strangers' Gallery. You should be able to entertain people easily with a borrowed pack of cards before you start to move on to tricks like Strangers' Gallery. Otherwise you will end up putting yourself into awkward situations because you are limited to only the effects you have bought.
May I make my stock recommendation for beginners? Have a look at the DVD linked in my signature, Born to Perform. It contains all the stock moves you will need to perform with a pack of cards and once you've mastered them you will be a much better magician?
Sorry again if I sound harsh, I don't mean to.

EDIT: It's too hard for me to explain what a swing cut is in words without you knowing other basic terminology (Biddle Grip etc...) so I'll just stick to my recommendation of Born To Perform - which incidentally does have the swing cut.
