This loop relies on Basal Sliver to fuel its own recursive journey, converting each sacrifice into the exact amount of black mana needed to recast it. Pulmonic Sliver acts as the vital bridge, replacing the creature's trip to the graveyard with a neat placement back on top of your library so it never truly slips away. Meanwhile, One with the Multiverse transforms your library's peak into an active hand, letting you seamlessly replay the sacrificed Sliver over and over again without losing momentum.
