So ... the classic Erdnase/Houdini change? Paintbrush change, KM move, the "scoop switch", any number of mucks ... Most color changes could be used to do this. I'm not sure if I'm missing something in what you're looking for, but it doesn't seem like this should really be a challenge for anyone who's studied any foundations of card magic.
The KM move I had discarded because I wanted it be more visual. And until I do the KM move, the colour change won't clean up. All in all, KM discarded (tho I love the sleight).
The paintbrush I use changes the SECOND card for the TOP one, so...nope.
And yup, the Erdnase change, see...(I should have elaborated on what exactly I wanted, sorry...my bad
)
The scenario would be that I have a card at the top face up and the second card would obviously be face down, like the rest of the deck. Then I would need to do the colour change. So the way the Erdnase would look good was if the top card was face down as well, right?
But it looks really strange in the effect if I turned the card face-down and started rubbing it...would look out of place.
But of course it would look like a magical gesture, so the Erdnase is always an option I guess.
All other switches I know change the second card for top one...and I dunno any mucks or 'scoop switches'...please sue me for that
