Onslaught, released on October 7, 2002, kicks off the block with a strong tribal theme, focusing on creature types like Goblins, Elves, Clerics, Beasts, and Soldiers. It introduces the Morph mechanic, allowing creatures to be played face down and turned face up later for a cost. The set also brings back Cycling and debuts the original Fetch Lands, which became staples in competitive play. Notable cards include Polluted Delta, Goblin Piledriver, Patriarch’s Bidding, Ixidor, Reality Sculptor, and Astral Slide. With its mix of tribal synergy, impactful lands, and versatile mechanics, Onslaught set a strong foundation for the block.
