Basal Sliver (TSP-96) is a common creature Sliver from the Time Spiral expansion. It gives all Slivers the activated ability “Sacrifice this permanent: Add {B}{B},” effectively converting Slivers into a mana source. In Sliver tribal decks it doubles as a mana engine and a 2/2 body to contribute to the swarm.
