It looks like the four Leaguers will correspond to each of the four "good guy" classes, so it's just more thematically appropriate. Elise is a Druid, confirmed, and I bet Reno is a Paladin, Brann is a Hunter, and Finley is a Mage. It doesn't line up quite perfectly, but it's close enough.
I'd say Finley=Pally and Reno=Mahe, because Murlocs are usually Paladin cards and Dragons have been Mage cards lately :v)
It is triggered by any minion, not just Murlocs. And Pally has many cards that summon a bunch of Recruits at the same time.
Next: Must be a Beast.
Not very original, but...
Next: A Legendary minion.

ZardpzSpeakz went first, so I'll do a card with his art:
Next: A spell called Plague of Blood. It must be some sort of board clear that belongs to an EVIL class. The expansion must be SOU.
The lady who made the announcement is so serious that she is funny.
Edit: just realized my card is very similar to the card above...
Next: A Warlock Beast with Demon synergy.
Next: Don't let this awesome artwork go to waste. Obviously, it can't be Headcrack.
Next: Must be an oversized minion with some sort of limitation.
Helen Lovejoy approves this post.
Where X is the damage you took initially, of course.
Next: Must be a Mage legendary from Saviours of Ulduam called Reno, Dragonsoul. It must be related to Dragons in some way.
I'd say Finley=Pally and Reno=Mahe, because Murlocs are usually Paladin cards and Dragons have been Mage cards lately :v)
I like that the Quest rewards are Hero Powers. It's an interesting twist on the original formula.
Btw, I wonder who will the EVIL legendaries be. I hope it's not Rafaam and co, because that would feel repetitive.
Next: Shaman Legendary.
Alright, but you could be a bit nicer.
Next: do whatever you want.
Next: do whatever you want.
Next: GvG or BDP minion called Techno Dancer.
Next: A Shaman card.
She is basically a reversed Wailing Soul.
Next: Another version of Milhouse Manastorm from Rise of Shadows.
