I played a game with a questshaman. I got the quest completed and play double battlecry heropower and then Swampqueen Hagatha. My opponent (Priest) then play Seance on my played Swampqueen Hagatha, and plays his version. And now here is the kicker, he also gets the double battlecry effect. Nice one Blizzard.
Did he steal your hero power with Grizzled Wizard?
Either way, would be helpful if you had a replay of that game so we could take a look ourselves.
No, I had my hero power and besides he couldn’t do it like that without discounts as Swampqueen is 7 mana, and Grizzled Wizard + Hero Power would require 11 mana in total. And I had coin.
If you have a link to the game on hsreplay, or a screenshot of the interaction when it happened, then please hop over to the Bug Report forum (at https://us.forums.blizzard.com/en/hearthstone/c/bug-report/8) and report this problem there.
Eh, it’s Hearthstone. Lots of crazy things can happen.
