集合牌背变色

一副蓝色牌，摊开在桌面，展示双手是空的。只要轻轻从右往左一挥，牌面变成红色。直接看到整副牌变色。手经过的地方都会慢慢变化。效果上特别直观。

表演结束后，桌面的红色牌，可以完全交给观众检查。

Blue to Red Deck

A blue deck is spread out on the table. When the magician waves his hand from right to left, the blue cards turn red. Finally the whole deck changes to a red deck. The effect is particularly visual. And the red deck can be completely handed over to the audience for inspection.

Comes with gimmick cards and video instruction. Please prepare your own red bicycle playing cards.
