I'd hate to be that guy who just whines about a card because I just lost to it, but this seems like an exceptional card.
I play shaman at the moment, and was winning against a paladin, that is until he used sword of Justice.
The tokens made by his hero power traded with many of my high value units (juggler, totems, SSC), and I couldn't do anything about it without using several cards to clear his board. Of course, this gives the Pally a huge card advantage and I had no way of coming back.
Do you guys feel that SoJ provides a lot of value? Is it too slow? If it gave +1 health OR +1 Attack would it be more balanced?
I feel that as a turn 3 drop the SoJ gives a strong candidate and board advantage, and that the only counter that I have would be a swamp ooze.
