It clearly states on the card: "Battlecry: Put one of each Secret from your deck into the battlefield."
 
Well, I didn't have any secrets out--well, maybe one..? can't remember--but I have multiple secrets.  One of each type.  And it only drew five. 
 
What's up with that?  Is it a bug, or are they going to change the card to read: "Battlecry: Put up to five Secrets from your deck into the battlefield."???
 
(Apologies:  Can I just post it there from here, or repost?)
