I'm going to jump in here and say how much I love the principle behind X-ACT! From the spectator's point of view, Inexplicable and X-Act are the same effect. They are allowed to have the cards dealt down to a certain number, and whatever number they stop at, the card will match your prediction.
However, I personally like X-ACT a little bit more for the following reasons:
1. Less spectator management. With Inexplicable, there is a little more management on where the spectator can stop. With X-Act, there is no management! They name any number between 1 and 52, and once you pull the cards out of the deck, the "work" is done. You literally can freely and confidently deal down to their number, and it will match your prediction.
2. With X-Act, you can show the entire prediction card. You can literally pour it onto the table and see the entire thing. With Inexplicable, you have to hold the card when displaying it. Again, not a big deal, but I think X-Act is a little more "open" in it's display.
3. X-Act comes with an instructional DVD, and Mark Mason is a great teacher.
4. With X-Act, the gimmick is GENIUS! It literally does all the work for you, and it's very well made.
The only disadvantage with X-ACT is that you only want this deck to be used with this effect. It's not a borrowed deck, and therefore, you want to dedicate the deck for this one effect only. However, on the flip side, the RESET IS INSTANT! It's literally reset when you pick the cards back up, and you're ready to move onto the next table or next group to perform it again.
