I own this deck as well as the Invisible deck. Personally I like the Invisible deck a bit better.
The effect on the BW deck is really strong however. Once you were comfortable with either deck
they both make very strong effects. Watch the videos on both to see the diffence. As far as
difficulty goes, I would say the Invisible deck is slightly easier, but not really by much. Of
course other people have the exact opposite opinion of mine. Just pick which effect you like
better and stick with that.
