The Four Living Creatures- Territory Class: "Protect hand and deck from opponents. Each Upkeep, if you control Heavenly Temple or a Heavenly Temple Artifact, you may draw 1. Once per round, you may return this Hero to hand."
Can this card be returned to my hand as it is being discarded?
If not, what exactly is the point of that part of the ability? Is it to rid it of attached Enhancements or diseases? Don't get me wrong- The Four Living Creatures is a FANTASTIC card- but is that all that last part is there for?
