Singularity Rupture

Board wipes almost never do double duty, and that separation is usually deliberate: a Damnation clears the table, and if you want a mill payoff you cast something else. Stapling a symmetrical sweep to a proportional mill effect in the same six mana is the unusual move, and the proportional part is what makes it dangerous. Milling half a library rounded down is a percentage, not a fixed number, so it scales with what the target has left: brutal early against a fresh sixty-card deck, near-useless late once the graveyard has swallowed most of it. That decay is what keeps the effect from being a repeatable clock. The "any number of target players" clause matters more than it reads, too, since it lets the caster leave themselves untouched while halving everyone else's deck, or fold in a self-mill line for a graveyard build without touching an opponent at all. The sequencing is fixed and one-directional: creatures die, then libraries thin, so the wipe cannot be dodged by the mill and the mill cannot be redirected by whatever the wipe kills. It is a control card that wants to win two different ways at once, resetting the board while quietly setting a decking timer, and the blue-black cost signals exactly the deck that has both patience and no board of its own to protect.
