Elephant Graveyard

Arabian Nights is full of these: colorless lands stapled to a tribal regeneration ability for a creature type that barely existed when the set was printed. The design is a flavor artifact from a moment when Magic was still figuring out what a land could be, and what it could not. The regeneration clause is narrow to the point of self-parody: at the time of printing, the legal Elephant population was small enough to count on one hand, and even today the card asks you to build a deck where tapping a land for colorless mana and protecting an Elephant from a removal spell is a tradeoff worth making. What the card represents is the brief window where Wizards was willing to print a land whose secondary ability would be functionally dead in most games, because the flavor of an elephants' graveyard was worth the slot. The design language moved on quickly: utility lands since have been built around abilities that scale with any deck, not abilities that gate themselves behind a creature type the format may never support. Read it as a relic from the years when a card's name and image could carry as much weight as its rules text, and the rules text was allowed to be a joke the flavor was telling.
