Foils occurred in their rarity slots (common foil in a common slot) in every 12 boosters for common foils, in every 20 boosters for uncommons, and in every 40 boosters for rares. Released in February 1999, Urza's Legacy is the second set in the Urza's Saga or Artifacts block. It is also the first set to include Foil cards. The set contains 143 black-bordered cards (44 rare, 44 uncommon, and 55 commons). Urza's Legacy is a Magic: The Gathering set, second in the Urza Block.
Urza's Legacy continues the prequel storyline started in Urza's Saga, following Urza's quest to fight Phyrexia's godlike master, Yawgmoth, and his plans to conquer his home world, Dominaria. After an attempt to manipulate time goes catastrophically wrong, Urza searches for more allies as he builds a skyship to lead the war against Phyrexia. While he is away, the people of his Tolarian Academy have to battle a Phyrexian infestation on the island itself. The story of this set is recounted in the book Time Streams.
Urza's Legacy expanded on some of Urza's Saga's mechanics.
Numerous cards with Echo had additional effects when they came into play, making it often useful to cast the cards without having to pay the echo cost on the next turn. Also, three non-creature artifacts were printed with Echo.
More "Sleeping" enchantments were introduced, including four that turned into creatures, and one of each color that produced various powerful effects when triggered.
Memory Jar — After many powerful cards from Urza's Saga and a few preceding sets were banned, the DCI was wary of more such combo cards. As Randy Buehler states in an article about the banning "players began leaving the game in droves" due to the dominating presence of combo decks at the time (nicknamed "Combo Winter"). Memory Jar was expected to herald new combo decks and mere days after Urza's Legacy became tournament legal an extremely fast combo deck built around Jar was showing up. The DCI decided that another three months of combo decks dominating the tournament scene wouldn't do and banned the card outside the usual schedule in what has been the only "emergency banning" in the history of the game.
