I am kinda scared to use anything in my performance that leaves you dirty in the end because in the back of my head i always feel like someone will say "let me see the deck", or something like that.
Here is the thing... if you perform magic in a way that makes your audience seem tricked, they will seek the method. If all you talk about is what the you are doing with the props, the audience will focus on that and think about what you are doing with the props. That leads them to thinking that the method is what you are doing or the props. Unfortunately, using say-do-see patter (you say what you are going to do, you do it and you tell the audience to "see" the effect) is how most effects are taught.
Structure your routine in such a way that you throw suspicion onto something else other than the prop, and in such a way that they admit that they don't suspect the prop.
The problem with that is that you are suggesting that there IS a method. Having the audience think about the method kills any possibility of astonishment. Even if the method isn't the correct method, they don't know that. They will think that they figured it out.
The solution is to give the audience something else to think about as part of your presentation. Make your presentation meaningful.
Additionally, treat any gimmicked props as if they aren't. If you have a one-way deck, have a spectator shuffle it (heck, they can even shuffle a Svengali deck). If you are using a DB card for a perfect force, have the spectator do it in their hands. The more you treat the props as normal, the more the audience will assume they are normal.
For the Invisible Deck, have a spectator hold the deck while the card is being though of, have the spectator take the reversed card from the deck (this puts the focus on the card rather than the deck), casually take the packet above the selected card and move it to the bottom of the deck (this makes the bottom of the deck look normal) and then put your focus on the card the spectator has, letting the hand holding the deck drop to the side of your body out of view. Beginner magicians always tend to telegraph when they are doing a sleight (they look at their hands) and when they are using a gimmick (the look at the prop and try to get it away from everyone as soon as possible).
Finally, learn to enjoy being dirty. Part of that is letting the audience handle the props. Seriously, I'm laughing inside when I have an audience member shuffle a one way deck. Part of that is just learning to enjoy the risk - you can always say "no" if they ask to see the props.
