Enduring Sliver

Outlast has always been an awkward keyword: a sorcery-speed tap that trades a full attack step for a single counter, so slowly that it rarely pays for itself on one creature. The trick this design lands on is distribution. Granting the ability to every other Sliver you control means an entire board can grow in parallel, and the shared symmetry that defines the tribe (Slivers famously hand their abilities to each other) is here reversed: instead of the lord passively broadcasting a keyword, the lord gives the whole team a repeatable, activated growth engine. The tension is that outlast still competes with attacking, so a board built on this plan wants to be wide and patient rather than fast, banking counters across many bodies during turns it is not swinging and then converting that stored size into a single overwhelming push. That makes the card less a beater than a slow accumulator: the tribe's typical problem is running out of gas in a stalled board, and a way to keep sinking mana into permanent growth answers that directly. As a two-mana body it exists to be cast early and left back, the anchor that turns idle Slivers into an escalating threat rather than a static one.
