So I realized that I said something wrong in the previous video. The card that gives you 2 extra cards per turn is actually "Liyue Harbor Wharf" not "Jade Chamber". I'm really sorry about it.
However, this is the walkthrough of Tavern Challenge: The Oceanid's Concern in Genius Invokation TCG gamemode. You can unlock this challenge by completing the Ascension Challenge: Advanced which is really easy, but if you need help on that PLEASE let me know.
