They were smoking Cuban cigars, thinking how do we make more money?
"Oh I know," says an employee. "Let's release some broken decks to get all the people that care about PvP to buy the pack and build the deck, then we will later limit/ban some of the cards to balance."
Manage: "That's perfect, I knew there was a reason I hired - what was your name again?"
It's why I've stayed F2P since starting. Not worth spending money trying to get a card to later have that card semi-limited/limited/banned. I'm fully expecting Spellbook of Judgement to get banned, but it may depend on what other spellbook cards the pack has besides the datamined ones.
