Odyssey, released on October 1, 2001, kicks off the block with a strong focus on graveyard interaction and resource management. It introduces the Threshold and Flashback mechanics, encouraging players to fill and use their graveyards as a strategic resource. The set leans heavily into card advantage and subtle synergy over raw power. Notable cards include Entomb, Patron Wizard, Call of the Herd, and Buried Alive. With its deep, skill-testing gameplay, Odyssey marked a shift toward more complex and long-term strategy in Magic.
