Card magic - or "Cardistry" is progressively advancing and it's always exciting. New techniques or sleight of hands are being invented, and the old ones are regularly revised to a higher level. One example is the color change (for non-magicians, it means "card-changing"). There are some recent updates of the skill, and some are really, really beautiful.
Bertram Change performed by David McLeod. So flawless isn't it?
This is pure madness. Insane card change originally by Daniel Madison.
Last but not least, this Snap change of Aces is ultra-visual. Done with cards facing up! Speechless! ;)
