In this cool hoard pack you will be able to win houses such as the ones in bundles, and the ones in the crown shop. Obviously you won't get houses every time you buy it, so you will also get, treasure cards, pets, pet snacks, armor, and wands!
The idea has merit, but it's asking for too much. I think it would be really cool if they designed a single unique house and put it in a new hoard pack though. Make it like super rare and the only way to get it would be through the hoard pack. I think it would boost sales on the pack a lot.
