This would be Really cool
That's definitely a cool idea, and it's something Magicians could probably use, because they don't have the best initiative. I would reword it though, like, "You may search deck for Divination. Reveal a Pale Green Enhancement from hand. Once per battle, you may interrupt the battle to play that card."
I added may for the search, but the rest I think I prefer my wording to yours, no offense. Mine allows for the possibility of playing another copy of that card with the "ITB" gain if the opponent manages to get rid of the one you revealed, whereas yours does not.
