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!
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.
