oh I love these things
one of the Pokemon Mystery Dungeon games had a "Reviser Seed," which plays the same animation as a Reviver Seed, but then reveals "lol, you're still KO'd"
explorers of sky had several of this kind of thing. along with the reviver seed there were also ones that inflicted positive or negative status effects or just did straight up damage. the worst was the "oren berry," which is of course the lookalike for the oran berry. my dyslexia wasnt as bad back then but man did that one get me a ton
