The first time you cast a spell during an opponents turn, you get to look at the top two cards of your deck
A perfect curve for this deck would look something like this: Turn One: Duke of Weselton or Sergeant Tibbs Turn Two: Flynn Rider or Cruella de Vil Turn Three: Peter Pan Turn Four: Aladdin, Prince Ali or Aladdin, Street Rat Turn Five: Aladdin, Heroic Outlaw Turn Six: Genie, on the Job or Lefou, Instigator to Protect Aladdin You'll almost certainly be in top deck mode at this point, but there's a good chance you'll continue to pull high-impact cards like Kuzco, Tigger, Genie, and Aladdin throughout the rest of the game
Number Thirteen This actually does cost 6 mana, rough, with no built-in reduction cost
It has two abilities, the first of which is Focused Energy, which allows you to play Merida, Wisp Conjurer exterted to draw a card
Blue is getting another nice Curiosity effect this set in Enduring Curiosity, so this Room can provide some nice redundancy in a deck looking to capitalize on that
