Magic Tricks

I have to be honest, I didn't care about Woody's stack, since I've been already using Juan's Mnemonica for years and I love it. Woody's stack is more oriented towards gambling routines, which isn't my thing, but if you like that style of routines, go for it.
I got this book mainly because of the Siamese stack, and holy shit, that chapter alone is worth the price of this whole book. If you already know a mem deck, get this book and study that chapter and you'll be performing miracles in no time.
If you want to learn a stack, Woody's it's easier to learn compared to Juan's and Aronson's so it's a great option.
