This is the card that inspired my design. I wanted to make a
card that reduced each color for meeting a specific condition, but in the process, decided on this 4-color variant of a universal removal spell instead. Years ago, possibly on the motherboards, someone posted a cool card I still remember: an enchantment that gave all your 1/1s a benefit, all your Saprolings (I think, could have been another type) a benefit, and all of your green creatures a benefit, the idea being that 1/1 green Saprolings got all the benefits while your other critters only got some. It makes for neat limited card, where assembling the perfect specimens isn't always easy. Anyway, my card isn't anything like that, but that's where my mind went. I opted to leave planeswalkers out of the equation since they never share types with other permanents, and blue out of the equation because it sucks at permanent removal. Cheers!
