At the start of your turn, if The Librarian is face down in your arsenal, you may turn him face up.

Once per Turn Effect – Whenever you create a Spectral Shield token, draw a card and put a lesson counter on The Librarian. Then if there are 3 or more lesson counters on The Librarian, banish him, search your deck a specialization card, put it face up into your arsenal, and shuffle your deck.
