Descent of Dragons Card List & Guide
Deathrattle: Gain an empty Mana Crystal.
Does not work with temporary mana like innervate
Mike Donais Senior game designer at Blizzard Entertainment has confirmed this "It does not count those temporary mana crystals" (talking about innervate here)
This card only works with actual real mana, not that fake stuff.
Potentially devastating. Potentially amazing. Balances out as an OK card.
Mass Dispel anyone?
Or worse, Vanish
Devolve still sucks but no the worst one xd
