From what I can tell, there isn't really much value to having decorations on your board-- they take up space yet don't yield any magic. They look nice, but that's about it. Their main value is trading for elixirs.

Note that some decorations only give back 2 elixirs AND cost a lot of magic to exchange, so don't bother putting those in the cauldron. But some rare decorations give quite a lot of elixirs (up to ~700 I think, though that may be for a rare concession shop).
