I see that today's daily prize is Dr Freakenspleen, and before that we had the Scream of Halloween, the Daunting Pumpkins and Windmill of Evil. All those prizes where (grand) prizes of previous Halloween mini-events and players had to complete the events to get them. And IMO they should be unique buildings and not something one can have a whole field of if he/chooses. I absolutely don't mind they are back so that people who didn't play that event can also have one (I had never had the Scream, so I'm glad to see it), but they should be amongst the grand prizes, between artifacts instead of the 3 runes and other similar filler prizes. That way everyone could have 1 but not have entire rows of Freakenspleens or Screams. It really devalues those original buildings and the effort we've put into getting them.
