When Ominous Traveler enters the battlefield, draft a card from Ominous Traveler's spellbook. That card perpetually gains "You may spend mana as though it were mana of any color to cast this spell" and "When you cast this spell, return a creature named Ominous Traveler you control to its owner's hand." Ominous Traveler's spellbook includes the following cards: • Dominating Vampire • Vampire Socialite • Stromkirk Bloodthief • Falkenrath Pit Fighter • Wolfkin Outcast • Howlpack Piper • Tovolar, Dire Overlord • Patrician Geist • Shipwreck Sifters • Steelclad Spirit • Heron-Blessed Geist • Archghoul of Thraben • Champion of the Perished • Headless Rider • Bladestitched Skaab
