While the number of 1-cost spells is fairly limited in all classes, making the outcome somewhat predictable usually, it's still a very slow card. You get rather poor stats and need extra mana for the spells, which will be not as impactful anymore around the point you can play this.
If you just need more dragons in your deck, maybe, but I don't think this card will be used much.
A few classes benefit more from this than other obviously. In my estimation I think Mage can really utilize this. Cyclone mage is an obvious thing. Between Mages new 1 mana spell and chenvalla (which is looking better now that we have seen this plus their new 1 cost spell) I could see some dragon/cyclone mage deck maybe coming into being.
