Hello. This is my first post on this forum, I hope I don't break any rules.
I think there is a missing edition: on magiccards.info it is called "Hachette Encyclopedia Inserts", it came with an italian magazine published about 8 years ago. Its symbol is a pegasus and the cards are all white-border. I'm not sure if it is tournament legal, on Google I found many sources stating this edition is legal, but I couldn't find any wizards' statements about it.
Should deckbox add it to its database?
