Obviously, in Quest decks, the goal is to complete the Quest as soon as possible. Raptor Hatchling has the potential to generate more one drops. Springpaw is two one drops. And if the minions affected by Helpless Hatchling still count toward the quest it can speed up how many cards you can play. Helpless Hatchling could hit Halazzi or Baku, but I think the average value of the card is worth more than the worst case scenarios.
I feel like most people underestimate the synergies Quest Hunter is getting, but I may just be too optimistic. When I was thinking about the Quest, I noticed very few even cards and decided the aggression from an upgraded hero power would be more valuable than the even cards. Very open to critiques, this is just a fun idea I had.
