This dazzling sequence turns Sliver Queen into a self-sustaining token generator by leveraging Agatha of the Vile Cauldron, whose passive cost-reduction makes the Queen's ability cost just {1} instead of {2}. Manaweft Sliver provides the essential mana engine, allowing the newly created tokens to tap immediately for the {1} required to keep the loop going—a feat made possible because Heart Sliver grants all your Slivers haste the moment they hit the battlefield. Together, these pieces bypass normal mana restrictions to flood the board with an endless army of tapped Slivers.
