Yes, that would allow all those colors. Also, the cards where the symbols are there but just black also would count. There is a porygon that one if my friends use, I can't remember the set.
This seems like the best place for this.
If your not interested, move along. Hating on something someone else enjoys just because you don't is a waste of breath. There is another 100 card singleton format that I tried to play before doing this, It still suffered from many of the power creep...
