Hmmmm....
Double-up... HMMMMMMM....
I am *inclined* to go with Zatanna, but that is not a solid opinion. Mordo is nothing to sneeze at, and while Z has a number of impressive feats, this would not necessarily be a given; with prep, I think he'd take it; off-the-cuff I think she's faster on the fly/has better finesse.
I might have to amend my opinion later...
