A new mishnah! If one slaughters an offering with intent to leave part of it for the next day - whether blood or parts of the animal - or to remove them from the Temple, the offering is subject to a dispute whether it is valid or not. There's no verse to disqualify this case, for example. Plus, when two verses appear to teach the same thing - in terms of not leaving the offering overnight. Also, one who slaughters an offering with intent that people who are ritually impure would eat from it - that offering is invalid, especially because this intent kicks in before the blood is even sprinkled for the offering. Which leads to the question of pigul vs. other invalidating concerns, such as the given person's impurity.
