Whether thats one of the Karador decks, Old Stickfingers, or any of a number of other decks in which I like to mess with the graveyard, Sword of Once and Future will star
13x lands that can produce white or black 1x land that can enter as either white or black (Brightclimb Pathway // Grimclimb Pathway) 9x lands that produce black mana One of them being Urborg, Tomb of Yawgmoth, which will make all lands on the battlefield a swamp, in addition to their other types Two of them being MDFC cards (Hagra Mauling // Hagra Broodpit and Agadeems Awakening // Agadeem, the Undercrypt) 6x lands that product white mana 5x utility lands For utility lands, there is the Dark Depths / Thespians Stage combo mentioned previously

The second exception is Special Guest cards, which have a small chance to appear in the Play Boosters (1 Special Guest in 64 Play Boosters), which are included in the Starter Collection
