Even if this little guy can't take out a creature, it's always worth using its ability since it will cause the opponent some life loss. It's like a Prodigal Pyromancer that hits two things at once. However, the ability becomes useless if your opponent has no creatures to target. Then again, if your opponent has no creatures, this card will still turn sideways to make them lose a life but though attacking instead of though its ability. All in all, it's a pretty cool card.
Pros: Pyromancer that effectively hits two targets
Cons: Ability is useless without creatures
