Everything was performed great, but the "pass" was not a pass at all. It was just an overhand shuffle control, which is used all the time and is a classic move. Also, why do you use, in my opinion, some of the worst cards ever made? I bought a deck of these a while back, tried them, hated them, and haven't touched them since. haha
Because some people like the idea of a card rising to the top of the deck(going to pocket, transforming, or whatever) without any visible handling of the deck after the card is inserted in the deck. It's just cleaner is all.
Not necessarily. Inserting the card, then shuffling the deck means that something happened to the cards. If you, for all intents and purposes, simply inserted the card into the deck, squared it up, and set it on the table, then nothing happened to the cards.
