Caverns Below (Legendary Un’goro Rogue Quest) is being nerfed soon. It’s changing from “play 4” minions to “play 5” minions.
I’d link directly to the announcement but our forum software is choking on the link, so I’ll just quote it instead:
[quote=Blizzard]In an upcoming update, we will be making a balance change to the Rogue card: The Caverns Below.
The Caverns Below now reads: Quest: Play five minions with the same name. Reward: Crystal Core.
Since the release of Journey to Un’Goro, Hearthstone has enjoyed a wider variety of competitively viable classes and decks than ever before. We’ve been monitoring overall gameplay, and we’ve decided that—even though everything is varied and many decks are viable—a change to The Caverns Below is still warranted.
The Caverns Below is uniquely powerful versus several slower, control-oriented decks and played often enough that it’s pushing those decks out of play. This change should help expand the deck options available to players both now and after the release of the next expansion.
Note: The Caverns Below will be eligible to be disenchanted for its full Arcane Dust value for a limited time after the next Hearthstone patch arrives.[/quote]
EDIT: Duh, I am mentally deficient today.
And in completely unrelated news having nothing to do with this change whatsoever, here’s a brief tutorial on the difference between playing a minion vs summoning a minion.
The play/summon thing is a distinction that has always existed, but except for a couple small exceptions, it has never been emphasized all that much until various Un’Goro cards (mostly class legendary quests) utilized and exploited the differences between these methods of getting cards on the board.
All cards that play or summon a card explicitly tell you which they’re doing when they’re putting minions on the board. But if you’re unsure of the difference, here’s a brief description of the differences between play vs summon:
Play: You actually play a minion card that puts that same minion on the board.
Summon: There are lots of ways to summon a minion (including ‘playing’ them, as all played units are summoned, but not all summoned units are played):
Spells: Such as Jade Shuriken, Resurrect, Unleash the Hounds etc.
Triggered Summon: Patches the Pirate, Violet Teacher etc
Battlecry/Combo: Murloc Tidehunter, Defias Ringleader etc
Deathrattle: Harvest Golem, Jade Swarmer etc
End of Turn: Imp Master, Moroes etc
Hero Power: Shaman and Paladin hero powers
Inspire: Kodorider, Truesilver Regent
And lots of other easy ways I’m probably forgetting.
Legendary Quests that require one to play minions:
Hunter, Rogue, Warrior
Legendary Quests that require one to summon minions (played minions also count as summoned here):
Druid, Priest, Shaman
