Hi! I'm a new magician currently learning card magic. There's one trick I saw performed by David Blaine that I'd quite like to learn right now; I haven't been able to find a name for it that I could look up, so I'm hoping someone could help me here Based on my currently mediocre knowledge of card magic, I assume that he simply has the deck pre-arranged in B/R/B/R order, and alternates between single lifts and very clean double lifts. Is it really that simple, though? When I attempt it, I often worry about my cards bending or sliding to reveal the card underneath - doing this cleanly seems incredibly difficult. Is there another explanation, or is this just a practice makes perfect scenario? Thank you!
