Remove some redundant variants

[TheDaniMan]

Synesthesia & White is currently the same as Synesthesia & Null. I think more logically white cards should respond to the color clues that match the number of the card, but if not then maybe such identical variants can be removed. Similarly, gray is the same as dark null. Also, here are some other identical variants I can think of: 2) prism & X (3) = rainbow & X (3) = amiguous & X (3), where X is any of white, null, light pink. 3) extremely ambiguous & rainbow = extremely ambiguous & prism = extremely ambiguous. I may add more if I think of more.
