I liked it a lot! It's not so difficult (btw, a little practice as for ALL Magic is due) it's
deceptive and can be put into real-world-use, if you like it.
Beside that, I liked most the fact
that the Shuffle can be used as a control also; really devious and practical.
It's a little
"flashy", but if you're into that kinda things, don't pass this by
