good: I like to see people still doing color changing decks their fun and awesome. You have a good version. Improvements: I have no intention of hurting your self-esteem (much unlike magic castle; strict standards) but only have the means to help you. First a mini flash at 0:36 which makes spectators go "wha?". Second, as stated above you gave no reason to why you either searched through the deck nor put the king through the center ( pattering or talking about how the king is special may help...). The color change is good but we all know it has angle issues; try gregory wilson's snap change; covered by right hand by all angles the top card flips over within snap motion and the later shown to have "changed") which would fix almost all angle issues with that. Lastly, stop saying "allright". Yes we know it's hard to be on camera, but it does not do anything to the effect. Try going without saying that "word"....allright? :D

This has been done more than once. The latest that I've seen it in print is Nemesis by Sam Webster.

Don't know why you would need to look through cards before "placing" the king in the "middle". BUT I did "like" the fact that they changed color.

I have seen ideas like this many times.. I honestly do not really like this at all. 1/5*

Dont like this much at all. First thing that comes to mind is, "let me see the rest of the deck." Just my thoughts
