So I am practicing some manipulations and ideas for tricks but one thing that I am struggling with is turning a card over in specific situations. What I mean by this : Selection is chosen from a dribble, I peel back their card and slide out a random card as if it is theirs onto the left hand packet and jog it like it is their card. I then do either clipshift, get a break or get the card to the bottom but I have also found I can just flip their card at the same time as I outjog their card and close the packets together so it is like their card somehow is upside down in the deck without doing any extra moves. My issue is that I can't get the turn over smooth and was wondering if there are other ways of turning a card over in 1 hand or between 2 hands while each hand is holding half of the deck. So my left has has the bottom half, my right hand is holding the top half. I am aware of card turn overs in the guise of turning the deck over in the dealing hand. Also the double lift turn over I forget the name. I am just looking for other alternatives, one handed or two handed but preferably card turn overs while holding half a deck in each hand.
