New Mage Legendary Minion was revealed by the GameStop.com site (Source).
The card seems to be oriented towards a Control Mage deck. It's a late game value generator - unless Silenced or stolen, the Tokens will generate two random Legendaries. However, the Tokens have 0 Attack, which means that Mage won't be able to attack with them. They will have to be killed by the opponent (which likely won't happen, unless the board needs to get AoE'd) or pinged down by the Mage's Hero Power.
