What makes the current reborn quest powerful isn’t really the reborn minions themselves, but what you can do with the hero power. There are enough reborn minions from Uldum alone that allow Paladin to fairly easily complete the quest. Right now, they are using cards like Mechano-Egg and Mechanical Whelp as the payoff cards once the quest is complete. It’s likely we’ll make other cards that are great with the quest payoff over time, making the quest feel a bit different with each set.
