It looks like a good expansion but, the dungeon row of cards doesn't change a lot during a 2 player game as they are only replenished when they are bought or fought. I have come up with a better idea and made up a set of cards, you pick one a turn when entering a dungeon room that has nothing to offer, these cards have things like, flip a depth square, portal, regain full health, - 2 clank, dragon attack, found 5 gold, I have 50 in total, cost nothing.
