The result for seeing more updates from pages you actually LIKE is to start using interest lists. I created a list for Mini treasures updates, feel free to subscribe it or create a list of your own with all of your mini related pages on it :).
The place where you create the Interest list is in the beginning of the page next to Like:
We also have a group in Facebook, you are welcome to join it too. :)
