the setup is so natural. Its like a top change or half passing one card. Even effortless misdirection like not looking at the deck when you do the setup is sufficient.
Unless your talking about the setup for the setup. Lol thats a different story.
I think an elegant approach to the switch is just as a casual color change. A lot of magicians will do color changes in an off the cuff manner, sometimes without a selection.
