I just finished a game with Page and Divine Wind. I had a Page and a Treasure hunter and opponent had 2 Treasure Hunters when the Divine Wind exchanged all of the cards in the kingdom. He ended up trashing my Treasure Hunter before I could play it.
His page-lineage cards continued to upgrade throughout the post-divine winds game, but my page would not.
