The Deathrattle mechanic was a major focus of Hearthstone
's Naxxramas adventure pack. While it isn't the central theme of Goblins vs Gnomes, Blizzard's latest look at the upcoming expansion
makes it clear there may yet be strong synergy with Deathrattle cards. The expansion preview highlights three cards in particular:
Feign Death Trigger all Deathrattles on your minions.
Lil' Exorcist Taunt. Battlecry: Gain +1/+1 for each enemy Deathrattle minion.
Scarlet Purifier Battlecry: Deal 2 damage to all minions with Deathrattle.
Feign Death (a Hunter card, naturally) has the potential to be extremely powerful -- not only with Naxxramas cards, but also with the Hunter's own Savannah Highmane, which is already a powerhouse unto itself. Savannah Highmane on the field with Baron Rivendare followed by Feign Death would result in a full board of minions. Lil' Exorcist and Scarlet Purifier seem more of a reaction to Naxxramas, a small balance to some of the adventure pack's more powerful cards, though your Scarlet Purifier triggering an opponent's Nerubian Egg might be bad news.
