I'd like to ask the group if they can help brainstorm on different approaches to vanishing the card. I'll list a few, but I'd love to hear about any other ways to get into this that you think of.
The time honored method is to burn the card in an envelope. That's great, but in some situations fire is just not appropriate.
Kevin James uses the Double Card method which is detailed in the instructions that come with the Intercessor. I've been told that this is actually an old idea of Ed Marlo's. It works, but I'm not sure I want to depend on having a second contrasting color deck available, and it takes a while to deal all the way through the deck.
Where appropriate, another idea from the Intercessor instructions is to have a spectator tear up the card and take the pieces to the nearest restroom and flush them down a toilet. I kind of like this, although some will find it tacky.
There are numerous sleight of hand methods to vanish the card, which can be torn into pieces before the vanish. In some, a handkerchief is used as well. In others, the pieces go into a paper clip.
Finally, here's a thought of mine. It uses the nested set of folded papers called the Buddah Money Mystery. While it's a magic store item, put out by Royal Magic, it does not look like something that you got at the magic shop. It just appears that you got some papers and folded them up. There are two ways I've thought of to use this in conjunction with the Intercessor. First, the papers can just function to vanish the card. You unfold the papers, put the card into the smallest one, and refold the papers. When you reverse the process, the innermost paper is now empty. You find the card in whatever location you like.
The second use of the Budah Papers turns the trick into a very clean and extremely easy to do version of the Torn and Restored Card. You simply have the dupe card in the Budah Papers to start with. The torn pieces, minus the piece the spectator is holding, are put into the papers. They're folded into the nest, unfolded, and the card is restored. The corner fits.
Finally, one more thought on the use of the Intercessor. This may be the simplest and cleanest way to use it. Simply tape the Intercessor Gimmick onto your card box. On the side with the back of a card showing, of course. When you want to do some card magic, bring out the deck, remove the cards, and place the box on the table with the intercessor side down. When you're ready for the torn corner trick, force the appropriate card. Now pick up the box, and put the deck away. (Spectator is holding his card at this point.) Now, put the card on top of the box and do the corner tear there.
Whoops: one more suggestion: The Intercessor is made with two gimmicks. (Owners will know what I mean.) The idea is that it can be done left handed or right handed. However, since I always do it right handed, I replaced the card on the top of the gimmick with one that is only "Intercessored" in the upper right corner. Now if you tape that on the box, you have less to hide. In fact, when you have torn the corner almost completely off, you can tip the box down so that they can see the back. It appears that you're just holding the card on the box, and that you've torn one corner almost totally off. This display is extremely clean. Then, just a momentary necktie as you grab the corner and pull the card free of the box. You can table the box intercessor side down, or pocket it at this point and conclude your routine.
