So by color and rarity count today we have 2 white, 3 blue, 2 black, 6 red and 7 green double sided cards in magic as of now, each one of course is a different rarity that is for sure and each one of these is pretty darn interesting, each one also has a color indicator which indicates what color they are in their night time form, for example since Unholy Fiend is the nighttime form of Cloistered Youth you'd think it was a white card, but it's color indicator is black not white, some may end up having a entirely different color indicator in magic, again introductions to these 20 new cards are not necessary however we've been aware of them for about a week and well some of us already are sick of em, again the rules for the double sided cards are going to be below 711
