A visual close up magic deck designed by Federico Quintana and calls it The Transparency.
Similar to the “Acme Hole” by Llyod Barnes but this effect requires the black or colored sticker or and ends with the front of deck. Sometime the relfective can be revealing which forced me to re-think the simplier and purer illusion. This is when I came up with the new method….
The Transparency, you just hold a card and let the shadow beams through the hole and turn it over….magically the deck (both front and back) are completely normal and NO DIRTY CUT
