I understand completely.
I think theres a way of doing pips or something alongside the suit symbol (Wands, swords, cups, pentacles) - if you wantd to condider color for these, then it might be useful to know that each is associated with an element - Wands = Fire, Cups=Water, Sword=Air, {Pentacles=earth).
I think the tarot system has depth enough to make some interesting games
