Hmmm. You can use this card to translate Forbidden Tome a couple of turns quicker, all while refilling Mr. "Rook", Encyclopedia, Esoteric Atlas, etc. Can you use it to translate Archaic Glyphs faster? It say so put a Resource on it "as a secret."
It's a pity that it's pretty hard to get ES in a deck with Quick Learner. I'd like the chess motif....
