Oracle is a very unique and bold concept when it comes to the idea of a full billet peek. Within this method there are a few methods taught, one is a completely unfolded piece of paper peek with very strong psychology. While the main Oracle method that is being taught uses a regular sized sheet of paper folded into quarters. While this method is very bold is certainly flies over the head of everyone watching or participating in the demonstration. The method is so natural and unassuming you will be surprised how well it works, also the psychology of the effect is so well structured. This is a very well thought out peek, nice work on this piece.

If you need to get a lot of information read from a billet, this is the only peek you should even consider. It opens the ability to peek 5-6 pieces of information from one billet, then reveal them at different parts of the routine in different ways.

This is really good.

Seriously, it's invisible, one piece of paper, they write or draw or whatever, fold it on the table, they can check that you can't see through, you never unfold it, tear it, or do any funny move [no sleight of hand, no switch, nothing] and you can get your peek anytime during the routine, even surrounded. It's really that good.
The only downside might be that if you are performing somewhere where the lighting is poor, you might not be able to get a clear peek, but then again i haven't encountered that problem yet.

I don't really have that many peeks that I use often aside from acidus novus, but this one is one that use and will use very often.

Fraser and Ross give you a certain type of routine in which Oracle is best used, but I will add that this is a great peek for drawing duplication, especially if, as i said, you perform in dim lighting.

The bonus by Ross is a really, REALLY BOLD peek, I personally think it's genius, but it will not be for everyone, as it is, very **** bold. Worth a try tho.

And it's a bargain.
