>>27714604Because Pyukumuku has 79 HP at lv. 23, we can tell it has between 85 (if it has 31 IVs in HP) and 100 (if it has 0 IVs in HP), assuming it has no EVs in the video.
With max investment at base 85, it should KO every pokemon with no investment and less than base 116 HP.
This means that most sweepers should be able to KO themselves unless it ends up getting good defenses too.
If there are EVs though, its HP could be as low as 55, but I don't think that's the case.
