Frenzy Sliver

Most Sliver lords stack stats or hand out evasion; this one weaponizes the act of getting through. Frenzy lived almost entirely on the experimental fringe of design, a keyword built to punish the choice not to block, and folding it onto the Sliver chassis is the rare context where that punishment actually bites. The trigger fires the moment a Sliver is declared unblocked, pumping its power before combat damage resolves, so the threat is structural: blocking eats a creature, not blocking eats more damage than the unbuffed body suggested. That fork is exactly the position a wide Sliver board wants to create. When the table is flooded with attackers, an opponent cannot block all of them, and every swing they wave through grows on the way in. The grant is symmetric across all Slivers, friend and foe alike, the usual caveat with this tribe, but the asymmetry of board state does the real work: the player presenting more bodies is the one collecting the trigger, every combat. As a 1/1 for two, the body is incidental. The card is a static enabler whose job is to make a finished battlefield close a turn faster, converting the opponent's least-bad blocks into bad ones and turning marginal alpha strikes into lethal ones.
