If you look at lists of the all time most favourite and popular packet effects, you're almost
certain to find B'wave mentioned right near the top. It was created by Max Maven (aka Phil
Goldstein), and is a simple trick to perform. It involves just four cards, and minimal set-up and
handling is necessary, so it's very easy to learn and perform. It's largely all about the
presentation, as the spectator's selected queen is shown to be the only one face up, and then as a
kicker the remaining three cards are shown to be blank. It's similar to The Parade of the Kings,
which is an obvious influence, but the final reveal makes it an even stronger effect. B'Wave can be
performed either as a magical effect or as a feat of mentalism, the latter being the recommended and
most common way to do it. With the right patter, it can generate a very strong reaction. Excellent
for strolling magic, or for keeping in your pocket or wallet whenever you are called upon at short
notice to do a card trick. - BoardGameGeek reviewer EndersGame
