This wondrous assembly turns Lullmage Mentor into an absolute fortress against your opponents' spells. Whenever a rival dares to cast, you tap down seven Merfolk to trigger the Mentor's countermagic, which in turn creates a fresh wave of token fish to replenish your ranks. The true magic lies in the multiplicative stacking of Parallel Lives, Primal Vigor, and Bard, King of Dale: each token-doubling effect compounds upon the last, transforming a single generated Merfolk into an overwhelming eightfold swarm. With this exponentially expanding school at your command, you will instantly replace your tapped costs and lock down every spell your opponents attempt to cast.
