A new spell from Hearthstone’s upcoming expansion, Rastakhan’s Rumble, has been revealed.

Big Bad Voodoo is a two-mana Epic Shaman spell that allows you to give a friendly minion a Deathrattle ability. This Deathrattle effect lets you summon a random minion that costs one more than the one that’s destroyed.

If you use this spell on any minion that costs more than two mana, you’re basically making a positive play because the Deathrattle will bring out a minion that costs more mana than what you previously spent. And who can argue with adding a Deathrattle that lets you summon a free, random minion for just two mana?
