Sentinel Sliver

Vigilance is the keyword the Sliver tribe needed least and was always going to get anyway. The lords that anchor a Sliver deck hand out their bonuses to the whole board, which means the tribe lives or dies on going wide and pressuring multiple fronts at once; the standard tension there is that a swing leaves your team tapped and your own life total exposed on the crackback. This is the answer to that tension, granting the keyword team-wide so every Sliver can attack and still stand up to block. The effect compounds the way every Sliver keyword-granter does: a second copy is redundant on this axis, but each one is also a 2/2 body that picks up vigilance from its neighbor, so the redundant lord still attacks and defends in the same turn. The result is a board that turns sideways without ever lowering its guard, the kind of grinding presence that strips an opponent of safe attack steps. The body itself is unremarkable and meant to be: the value is entirely in the static ability spreading across a tribe built to flood the board, where one creature's keyword becomes the whole team's. It is the defensive complement to the more aggressive tribal grants, the piece that lets a wide Sliver board play offense and defense on the same combat step rather than choosing between them.
