Mistermath's Card Ratings for Voyage to the Sunken City:
5/10
This enters the list of cards that look like they could've been printed 3 years ago. This is, at face value, bad for the cost: draw 2 has always been 3 mana. Even tutor 2 has typically been 3 mana, when comparing to Sense Demons. The text on this card could even be considered a downside in the wrong deck and certainly in arena, as one might expect your lowest cost cards to provide you with the least fuel. Of course, the point is to get creative with your deckbuilding, and this can do powerful things like tutoring both Drek'Thar and Vanndar Stormpike, which, assuming you otherwise only have 5/6-drops, allows you to use Vanndar to discount them and then Drek'thar to pull them out of your deck. Besides that meme, this is also good in combo decks that want to tutor out just a few extremely important minions quickly.

Draw Zola + Vanndar for double discount.
