Hope names are as is as i don’t play in english. During the new Galakron campaign the second boss “Avalanchan” with 150 hp is broken.
I tried to play a deck with “Spirit-Breaker” (3mana, 2/5. Heroic power are deactivated) and… well… Avalanchan gave me a middle finger because he used its heroic power on it…
Btw, it doesn’t deactivate MY heroic power also. Seems not normal.
Also saboteur => Heroic power cost 5 more is not working either
Mindbreaker is the cards name you are talking about and it never worked in any of the adventures, same for Sideshow Spelleater and Saboteur.
Maybe the devs thought it would make the adventure bosses too easy if you’d be able to deactivate the enemies hero powers.
Mindbreaker is a card available from the Card choice in the current Tavern Brawl. So why is the effect disable if the card has been selected to be part of the adventure ?
They should replace it by something with a real effect.
