Making something out of ice could be problematic. For one, it won't look right from the sides so angles will be a real problem.
Second, you'd have to keep it cool until you needed to switch it with the deck, because if you have it stashed in a pocket it will melt pretty fast and look like you have wet yourself (not a good look for a magician!)
Ice melts very quickly at room temperature, and even quicker at body temperature so having it in your pocket or something would mean you'd need to do the trick VERY quickly.
I'd first think of a way to store it so it could be cool until needed. If you were in a closeup situation, Im not sure it could be done very effectively. If you were at a table or on a stage, then you could get a little cooler bag for it and hide it somewhere within easy reach.
To make one though, get some small pieces of rigid plastic, cut them so they match the size of the sides and bottom of a deck, wrap them in cling film and fill with water. Turn your freezer up high, if I remember right, the quicker water is frozen it retains more air, so it becomes less see-through.
Thats my take on it, if you really want to do it those are the hurdles I would foresee.
