Not bad, I wouldn't say I like it YET. The idea of this trick is good especially being impromptu but it needs more work. Why use 2 decks? Instead of having the spec pick a card out of one deck then you look through the 2nd deck to match their card, why not just show them a card from a different deck before they select theirs? For example, you can show them a single red backed card but don't show them the face, explain how its a prediction then place the card face down in their palm or on the table. Now have them select the card, then show the card you showed before making their selection is a duplicate of their card. Showing a prediction before the event takes place then having the prediction correct is a stronger effect then having them select the card then you take time to search through the 2nd deck to find its match. Hope this helps.
