While perusing gatherer today I came across the 15 special guest designed magic cards that came out in the M15 set. One card kind of stood out to me, Waste Not. Whereas the other cards are attributed to each designer (eg. Aggressive Mining has Markus Persson, Avarice Amulet has Penny Arcade etc.) in the flavour text, Waste Not has the following flavour text:
Designed by the Magic community
I am wondering how was Waste Not created, and why was it attributed to the Magic community instead of a specific person?
If it was contest type thing where many people submitted different card designs it seems odd that the winning design wouldn't have its designers name put onto the card.
