A new card reveal on the official forums: http://us.battle.net/hearthstone/en/...ntal-5-30-2013
The article speaks mostly about the Earth Elemental and the Shaman's Overload mechanic that makes him a sort of interesting card.
The real prize, I feel, was included at the end of the article: Lady Sylvanas Windrunner, The Banshee Queen
5 mana for a 5/5 is pedestrian, and I'm not a fan of the RNG in getting both a random minion from your opponent AND having to wait till Sylvanas gets killed before it triggers. The board might have changed a lot in that time compared to when you played the card. This gap in between the 2 makes the card less effective I feel, leaving your opponent open to take measures. For a legendary card I find it somewhat meh. I'm open to suggestions on how to make good use of these cards though.
