Unless it is decided otherwise, I see no reason a sorcerer can't use the same spell more than four times in a fight, though I'll have to have some system to restrict the use of spells like Fog and Time Warp/Time Walk. Decks will be recorded in the CS if you want to be that specific, but all I'm going to require is a specification of what color/colors the character specializes in and the type of magics they tend to use, like destruction and conjuration for example.
