Invasion, released on October 2, 2000, kicks off the block with a major focus on multicolor cards and allied color strategies. It introduces the Kicker mechanic and promotes flexible, splashy gameplay with plenty of gold spells and mana fixing. The set encourages creative deckbuilding with a mix of dual-color and domain-based cards. Notable cards include Fact or Fiction, Absorb, Urza’s Rage, and Fires of Yavimaya. With its emphasis on color synergy and impactful spells, Invasion marked a bold shift in Magic’s design philosophy.
