Alright, here's a small, quick effect with a double backer:
1. Take out
two contrasting cards. For this explanation, I'll use the QD (Queen of Diamonds) and AC (Ace of Clubs).
2. Place one card
face up on the top of the
face down deck. We'll use the QD. Get a pinky break
under the QD. Place the double backer on top of this. Place the other card (AC)
face down on top of the double backer.
Situation Check: Face down AC - Double Backer - Face up QD - Pinky break - rest of deck.
3. Push off the top card (AC) pretending you're doing a double lift. Take the card and do a pirouette flourish or anything that will greatly emphasise the singularity of the card.
4. Place the AC back on the deck
face up. Remember, you have a break under the QD.
5. Perform a
triple turnover - turning the top three cards over as one.
6. Take the top card off and give it a pirouette flourish (face down). Turn it over to show the AC has changed into the QD.
Ta-da! A simple transposition/switch effect.
Enjoy!

PS. I got this idea from Chris Hestnes' burnable top change thingy. You can see it somewhere in his "Chris Hestnes In The Studio" video. Although this is a little less convincing than his version and I think it's a completely different handling, I believe he deserves some credit for inspiring me. Thanks Chris!
