Le texte d'ambiance de la carte Old Fogey évoque une légende urbaine, impossible à sourcer (voir aussi cette anecdote), selon laquelle la carte Plague Rats, de l'édition Limited (Alpha), aurait été, alors qu'à l'origine le nombre d'exemplaires d'une même carte (hors terrains de base) n'était pas encore limité à quatre dans un deck, au cœur d'une liste ne comprenant que des Plague Rats, des Black Lotus et des Swamp, en proportions variables selon les versions.
Ces listes sont encore aujourd'hui jouables dans le format alternatif Alpha 40 (deck de minimum 40 cartes, sans limitation du nombre d'exemplaires de chaque carte).

Source 1 (Nazgûl - "In Alpha, Richard Garfield made a card called Plague Rats . [...] The intent of the card is that you wanted to play a lot of them in your deck since they make each other stronger. Remember, deck construction rules wouldn't officially happen until Wizards started up the DCI in January of 1994. In the super-early days, decks of nothing but Swamp s and Plague Rats were common.") - Source 2 (Hare Apparent - "When Magic first came out, there was only one deck-construction rule: your deck had to be a minimum of 40 cards. [...] The lack of rules meant there weren't any card restrictions. A deck could have as many copies of a card as it wanted. Plague Rats was clearly designed with this in mind. One of the popular early decks had only three unique cards in it: Swamp , Dark Ritual , and Plague Rats. [...]")
