There was no need to nerf it, this card is really sad next to graboid (not exactly the card to use as baseline as its indeed op, but the difference is just way to huge). without use of the ability its a bad golem, with ability you pay effective 8
(duo cost adds 1) and a turn to get a 6 drop with an effect that will often destroy a pillar and doesnt occur unless sth you dont want to happen happens.
