Languish

Toxic Deluge is cheaper, scalable, and scores 70; Languish is a possible budgetless redundancy sweeper but rarely preferable.

Could be wrong if A creature-heavy metagame where paying life is especially punishing could make a fixed -4/-4 effect more attractive.

Toxic Deluge (68) is a turn cheaper and scalable, leaving Languish with only a very narrow no-life-payment niche.

Could be wrong if If low-life control mirrors and small-creature boards become common, avoiding Deluge's life cost could matter more.

A clean answer to many developed boards, but it misses larger threats; versus Culling Ritual it gains reach but loses mana and noncreature coverage.

Could be wrong if Optimized lists may favor more flexible sweepers, scalable X effects, or asymmetrical removal instead.

Four mana to erase most small and medium boards is a major swing, especially against tokens, though 4+ toughness creatures can survive.

Could be wrong if The unknown creature-size distribution, speed, and black mana quality could reduce how reliably -4/-4 clears the board.
