Baleful Beholder

A modal enters-the-battlefield trigger doing common-set work: it hands a heavy black body a floor of relevance no matter what the board looks like, and the split between the two modes is where the design earns its keep. Antimagic Cone is an edict rather than a clean answer: each opponent sacrifices an enchantment of their own choosing, which makes it a tax on their weakest permanent instead of a scalpel, and it reaches only enchantments, a category black has historically struggled to touch without a dedicated slot. Fear Ray points the other way entirely. A one-turn menace grant across your team turns a stalled board into a lethal swing, giving the card a proactive aggressive line for the games where there is no enchantment worth stripping. That either/or holds the kit together: on an enchantment-free board the sacrifice mode is dead, so menace keeps the card live; against an enchantment-heavy opponent, the edict does something while the six-power frame does the closing. Nothing about the rate is flashy, and neither mode is a guaranteed answer, but the modality is what lets a top-end creature like this find room in decks that want a threat with a fallback rather than a narrow toolbox piece.
