Then you fire off a semi-big Killing Wave and they splode. Not practical, but funny. If only because Tajuru Preserver acts as a sort of kill card, which was presumably not the intent.

They can just decline to pay and they won't have to sacrifice anything because of the Preserver. It doesn't force them to pay the life.

The combo with the Angel doesn't work either since they aren't paying the life to cast a spell or activate an ability, so it won't stop them from paying.
