Can Keyes do it again? Is his magic power strong enough?

After the first time I baffled two co-workers, they claimed I was using special trick cards. You can check out that video at the bottom of this post. OK, then how about round number two?

Here we go again. This time I never even handled the cards. I allowed Sara and Spring to randomly select nine cards of THEIR choosing. This way, it is impossible for me to mark or alter, in any way, these decided upon cards.

Here we go.
