Morgan & West developed perhaps the clearest presentation of a map walk!

Ten black and ten red cards are shown. The spectator mentally chooses any of the black cards.

Without ANY trick action, the chosen card disappears from the pile of black cards and is found among the red cards as the only black card.

The effect comes with Large Index Phoenix cards (with red backs), English online instructions with German, English, French, Spanish and Japanese subtitles (try turning on the German subtitles in the demo video)!
