It looks like Blizzard has begun revealing Hearthstone cards prior to release, with the first being the Void Terror warlock minion. This big bad blue dude absorbs the minions on either side of him, adding their power and life to his own. Even temporary power or health bonuses, like the +4/+4 from Power Overwhelming, are made permanent inside the Void Terror's blue belly. Need to protect from an incoming AOE attack? Gobble your other little minions up and let your Void Terror take the attack instead. It's a super simple and super powerful effect, fitting for a warlock and especially for Gul'dan, currently the game's sole warlock hero.
Check out all of our Hearthstone coverage thus far and stay tuned as the game gets closer to release.
