The card has a very weird interaction with hero cards, it plays the hero cards but the battlecrys don't activate. But the hero card is still "played" and the hero power changes.
In general any card with battlecry doesn't work even though the card says that you are "Playing" the cards.

Murozond doesn't activate battlecries. They just count as being played. So if you e.g. play Dr Doom your mechs won't have rush.
It's not a bug.
