It is finally confirmed that the cards for the Conflux Prerelease this upcoming January 31, 2009 will be Malfegor, the Legendary Dragon Demon from Grixis. As for the Conflux Release party promo card, it will be Obelisk of Alara. Check out the scan below, as posted by Coffee4am at Mtg Salvations Rumor Mill.
