If they want to use Ra's, they'd better use him properly. Comic book version.

There's no excuse anymore; Arrow shares a universe with The Flash, where superpowers are known and recognized. Ra's al Ghul's immortality is a key part of the character; turning that "immortality" into a trick would be just making a cheap knock-off of Nolan's version.
