Death Knights Will be Available in the Hearthstone Arena
In an interview with Shacknews, Mike Donais has confirmed you can use the Death Knight Hero cards in the Arena.
Quote from Mike Donais
Given what the Hero card introduces, I want to go ahead and ask, will it be allowed in Arena?
Oh yeah, these will be just like finding, say... N'Zoth in Arena. Or like finding some other powerful legendary, like Ragnaros, Ragnaros Lightlord, or Sylvanas. If you find powerful cards in Arena, these are legendaries that'll be in the legendary spot. Pick a good one and good luck! Maybe you'll get a Death Knight.
