Elemental Rogue quest? Return this once to your hand and complete the quest and you have a bunch of 1 mana 5/5. Elementals have a good sinergy with return to your hand effects too so... there might be something here.
This card let's you keep the elemental trigger burning across multiple turns rather safely. It might not see play in finely tuned elemental decks, but it's still a high value card and versatile enough for even the rogue quest or token decks!
