In No 25, It should have Minus Little Killer, because 20 and 24 have normal little killer, 22 and 23 have product little killer and only 21 has Minus Little killer. It is fair to choose Minus Little Killer next! Product Little Killers are quite easy, but I still like them a lot. Recently, I bought No 23 and No 24 to try.
