Prophecy, released on June 5, 2000, concludes the Masques block with a focus on lands and mana usage. Many cards scale in power based on how many untapped lands a player controls, rewarding careful resource management. The set includes Rhystic spells, which give opponents a chance to pay mana to counter their effects, and emphasizes slower, more strategic play. Notable cards include Rhystic Study, Chimeric Idol, Avatar of Woe, and Spore Frog. While less powerful overall, Prophecy offered unique mechanics and a distinct approach to gameplay centered around mana efficiency.
