I love this card. In my old red smashy deck, I ran 4 of these, 4 Spark Elementals, and 4 Hellspark Elementals and I usually hit my opponent for 9-12 damage on turn 3 and my opponent couldn't really recover from that. It's really great for burst damage as well as killing at least one creature. Now, it does die to Geistflame as well as first strikers and it costs 3 red mana so it's not very splashable, but it's still a great card.
Pros: Trample, smacks for a bunch
Cons: Dies to direct damage and first strikers, not very splashable
