Blackening Finale

Black Sun's Zenith is a concise board control tool that scales with the mana you commit. Casting X and two black mana lets you distribute X negative counters across every creature, forcing trades or outright removals and then reshuffling itself to the top of the library cycle. It reads like a surgical sweeper for sacrifice decks and aristocrat builds while remaining useful against token or go-wide strategies.
The card rewards planning and timing. Play it at the end of an opponent turn to leave your creatures intact if you pushed protection earlier or invest a large X to reset the board when a critical mass of small creatures threatens to overwhelm you. In Commander games from the Karlov Manor set it plays well as a repeatable answer when you can recur or shuffle your library to dig for a follow up.
