I tried to make a new deck using vampires, quintessence and shards of wisdom. Even though the ability "vampire" remains the vampires wont heal me anymore. I think this is becouse of the programming. The vampires are not actually attacking anymore but instead they cast spells and that's probably why they wont heal you. I just wonder was that intended or a bug? and is fixing this impossible? It would possibly require to recode the whole shard of wisdom.
