First, I have to admit two things. I've wanted to add cards across to my repertoire. And I wanted
some killer effects for Science Friction (maybe I'm not so personally creative).
Dan has
helped with both. He has clarified a variety of classic cards across versions and improved their
handling.
And the cards-across effects he developed with Science Friction are outstanding.
If you do platform/small stage/parlor (living room) magic, buy this.
