Echoing Calm

An enchantment-removal spell that quietly indexes the table by name: hit one copy, hit every copy that shares its title. The clause is a coincidence of design and the period that produced it. This sat in an era where artifacts and enchantments mattered, and the "all others with the same name" template gave instant-speed answers a way to two-for-one or three-for-one against decks running a full playset of the same enchantment. That bonus only fires when duplicates are on the battlefield, though: against a singleton, against anything with a unique name, it resolves as a plain two-mana instant-speed enchantment kill and nothing more. It belongs to a small cycle (Echoing Truth, Echoing Decay, Echoing Ruin, and Echoing Courage all carry the same name-matching wrinkle across their respective targets), and the whole batch trades reliability for upside in exactly the same way: you pay nothing extra for a clause that does nothing in formats where every card in a deck can be different. That is the design tension worth noticing. The spell wants a world of four-ofs to look powerful, and it answers enchantments at instant speed regardless, so it never reads as dead even when the sweep half goes unused.
