Discard has always been priced as spell or body, rarely both, and the friction is symmetry: a hand-attack spell does its work and is gone, while a creature that strips a card leaves something on the board to justify the tempo you spent. The trick this design uses is stapling the discard to an enter trigger on a cheap, expendable Elf Cleric, which turns a one-shot effect into a recurring one for anything that flickers, reanimates, or otherwise reuses creatures entering play. A 1/1 for two is negligible on rate, but the body is the point in the other direction too: it feeds sacrifice engines, elf and cleric synergies, and any deck that would rather cash the creature for value than attack with it. Compared to a straight discard spell like Duress, this trades selection for permanence and reusability; you do not choose what leaves the opponent's hand, but you keep a permanent that can be looped. That reusability is the whole argument. On its own it is a modest tempo play; inside an engine that keeps returning it, the discard compounds into a hand-lock that no single sorcery can replicate.
