I know most of you are in love with the invisible deck as the ultimate out, and it is a pretty cool effect, however me not owning one opened me to another suggestion. If you produce the wrong card in any manner (espeically on top) you can easily say that thats your "ambitious card" and routinely jumps around the deck. It must've replaced your card. Then proceed with the usual ACR. If you are good enough at it, people you soon forget about your botched revelation.

I like it! As long as you can make it sound convincing that what happened was supposed to happen. I'm not sure about just forgetting the previous trick. Maybe you could ask them what their card was, then during the ACR, bring it to the top and make the ambitious card change into it as the finale. That way at least you can happily end the trick. Apart from that it's a sneaky way to morph one trick that's failing into another trick which should work. Fortunately this requires no deck switch so is perfect for impromptu muck-ups.

I was thinking of working an ACR into some other routine. There are often those tricks where he magician has three chances to find the card, and if he fails the spectator gets to keep a prize. I thought: why not do an ACR in that situation? For the first attempt, the magician turns over the top card (not the selection). On realising that it is wrong, he puts it in the middle and turns over the next card (the same one!). This could be repeated once more if necessary (some of these tricks involve the magician not finding the card in the three attempts).
