Scourge, released on May 26, 2003, concludes the Onslaught block with a focus on high mana costs and spell-based synergies. It introduces the Storm and Landcycling mechanics, while continuing support for Cycling and tribal themes. The set rewards big spells and features cards that scale with mana value. Notable cards include Mind’s Desire, Dragon Tyrant, Stifle, and Form of the Dragon. With explosive mechanics and a dramatic shift in focus, Scourge provided a bold and powerful finish to the block.
