Dane mentioned that Da Undatakah will copy the effect of a Carnivorous Cube. Really? When N'zoth summons a cube, the latter minion is empty. Will the new neutral legendary actually steal the effect of a cube, which ate a minion and died?
Inb4 it's a fun card, especially in wild. I might play it in a deathrattle deck.
[Edit] My first thought was using this legendary in combination with Hakkar, the Soulflayer, but this is just a thought. If we look at the deathrattle minions currently and the ones from the next expansion, we might find a home for this legendary:
