Minion spell is good because it's always on curve, and as we've seen in the past, randomness isn't usually a great deterrent when it comes to minions. I can see it being auto-include due to its flexibility.
The damage spell would have been OP as fuck if you could target enemy hero, but minion only puts it below the damage curve. Probably won't get played without Flamewaker in meta. There's a rare chance it fits into a deck that relies on Antonidas since it's another fireball for 0 or 1 mana (if you can cast on 0).
Edit: Actually forgot Flamewaker was BRM, so it'll be in Standard, makes the damage spell a lot better
