If Fiery Conclusion isn't a good card, this sure as hell isn't either. At it's base level, it's a 5 mana Flamecast Wheel, which is slightly better, but it's still bad. If you have threshold, it's a non-sacrificial Firey Conclusion that costs almost triple. This would only garner 1 star if it said "creature or player". It's just really bad. Really really bad.
Pros: Non-sacrificial Firey Conclusion sometimes, better than Ember Shot
Cons: 5 mana, requires Threshold for max efficiency
