Check out the Chronicles, there are a few new ones there:
http://us5.campaign-archive2.com/?u=9da956a569c65d5b054e80642&id=e38ef24789Barkskin - +2 upkeep, cantrip that gives +2 armor and some other effects that aren't visible. Might be regeneration.
Vine Snapper - 7 mana slow cast, has a new characteristic 'rooted'
Ziggurat of Undeath - looks like the card revealed at GenCon, whenever a zombie kills something you can reanimate it.
Skeletal Archer - a bony royal archer.
Druids Leaf Ring
Togorah - cant read too much on this one, its a zone card, also rooted, but 21 mana, looks like a big deal. Has another new characteristic 'uproot' and vigilent. Also has regenerate 2, a d6 attack and looks like it dazes on 7-10 and stuns 11+. May also have intercept.
Grey Wraith - can teleport 1 zone instead of a move action for 1 mana. Gives a weak condition on 5+, but only a 3d6 attack.
Animate Death - this is the bring back from the discard card... yeaaahh! Looks like it costs half the creatures casting cost to animate it. Can't quite see what the creature's undead life is based on.
