Mini spell expansion 2 includes: Close Ravenenskeep and Draw 2 Cards.

Close Ravenskeep
Effect: Place this spell face down (bramble side up) atop Ravenskeep. While it is there, no wizards can move into (or onto) Ravenskeep, and no one else can cast this spell. At the beginning of your next turn, remove this spell from Ravenskeep and place it face up with the other spells; Ravenskeep is now open, and the spell is available again.

Draw 2 Cards
Effect: Draw the top 2 cards from the deck. Note: You will not draw to fill your hand to 3 cards at the end of your turn until you have fewer than 3 cards.

For playing you need Wandering Towers.
