Ugh, I am not a fan of these slow card previews coming from different sources like we had with TGT. At least this time they have an excuse in the form of needing extra time to work out the kinks of Standard and Classic card nerfs and whatnot.
Anyway, some new cards:
Hogger, Doom of ElwynnLegendary Neutral Minion
7 Mana 6/6
Whenever this Minion takes damage, summon a 2/2 Gnoll with
Taunt.
http://www.hearthpwn.com/cards/31117-hogger-doom-of-elwynnGoing for that Mech Bear Cat and Imp Gang Boss style, except it doesn't have 7 attack. I hope those Gnolls are also corrupted in some way.
Also a new Hunter card:
Giant SandwormEpic Hunter Beast Minion
8 Mana 8/8
If this Minion attacks another Minion and kills it, it can attack again.
"Wow, so a minion killed by this thing can attack again?". Joking aside, this looks like another card that a Hunter wouldn't want to add to their deck, but can become a great pull from Webspinner (Wild only), Ram Wrangler, Tomb Spider, and the like. For Arena balance, maybe it's for the best that it is an epic. Cute combo with Bestial Wrath and Stable Master, which lets it wipe the board and even go face.
