Yah that looks really like mine.
I think the method is a little different though.
It's all about what you get the spectator to believe.
There are so many ways that this trick can be done, that it's actually ridiculous.
The way you're going on sounds like this:
"Hey guys, I just came up with a colour change routine, but instead of an indifferent card changing into a selection, it's specifically the Ace of Spades changing into your selection."
Mmmmmmmmmmmmm.
