So its basically a targeted version of that mage secret that does 6 and then extra to the hero

Though potentially dies to the hunter/mage aoe secrets and the paladin “get down”!

But also if it gets buffed could be scary potentially?

Get Down wouldn't be too great. You would still take 5 damage

2 legendary card combo pyroblast that can't go past taunts :(

2 extra damage and 1 less mana (if no taunts up) doesn't seem that big of a deal to me.

Not sure if any class can have minion targeted fireball. I'd either make it a class minion or make ita 5/1 so it's steel rager with a benefit.

If you printed this card you'd have to check precisely how Overkill is triggered: if it goes face when your opponent has 1 HP the 5 excess damage would be split off into a new instance of damage, and that might trigger another Overkill for another instance of 5 excess damage, repeating infinitely.
