Hearthstone in the last 3 sets have added a card type that corresponds with the WoWTCG card types. The only types that are left are Locations and Loot.

With the previews revealing Dragon Soul (an Equipment - Item from the WoWTCG), Hearthstone has covered almost all of the WoWTCG Types...

WoW TCG	Hearthstone	Expansion
Hero	Hero	Base
Ally	Minion Cards	Base
Ability	Spell Cards	Base
Weapon	Weapon Cards	Base
Armor	Hero power / Spell Cards	Base*
Raid Cards	Adventure expansions	Curse of Naxxramas
Quest	Quest	Journey to Un'Goro
Master Hero	Playable Hero	Knights of the Frozen Throne
Item	Legendary Weapon (Dragon Soul)	Kobolds and Catacombs
Location	expected: Ongoing Ability / Resource Modifier	???
Loot*	expected: A special version of an existing card that provides an in-game content to WoW like a pet (or other cosmetic items)	???
