Altough i like the new version very much (because it is more fitting to unliving decks now), i feel that we lack with this an attack card for unliving decks. we have only 2 good uncommon damage unliving cards (Iron golem, clay golem)(With this i mean cards which are worth the cost for the damage), every rare unliving is just a bomb and then we have a few nice attack commons (petrified minotaur, flesh golem, conditional the mirrow golem, stone gargoyle deals just too less damage for its high cost). I miss here the chance for unvliving to become effective offensive, mainly because of the lack of offensive uncommons and commons which are worth their cost. Crystal golem was worth the cost because of its wall gain, which was indeed overpowered i think.
I would like to see some new offensive unlivings in this game to give unliving the opportunity to differentiate into more branches. Currently, the offensive variant of unliving is to hide in your shell ind slowly tear your opponent apart or hope for a rare. I think that Unlivings offensive tactic is too much rare depending now.
And on topic: leave the card as it is, it is fine now, just add a unliving in the game which looks like the old crystal golem, just with a lower wall gain :)
