'Legend' was originally just a creature type in these older cards, but in the future they would become essentially a supertype -- an extra adjective that tells you that this card falls under 'Legend rules', which means that only one copy of a card with the same name can exist on the board at any time (later changed to only one copy existing under the control of a player)
Copying spells has well-defined rules in paper, so even though there's a tracking issue with playing a card like this in person, it's not new territory for physical Magic cards
