Rush minion able to attack hero

I was playing the current tavern brawl adventure (Blackrock Crash) as shaman. At the second boss (Baron Geddon) I had a nerubian egg on the board. I then played a goblin lackey on the egg, giving it +1 attack and rush. The egg was still not able to attack the enemy hero since it was its first turn on the board. Then I used the ‘Evolution’ hero power on my goblin lackey it transformed into a doomsayer and suddenly my nerubian egg was able to attack the enemy hero. It seems as if removing the goblin lackey from the board suddenly enabled the rush minion to attack heroes.
Maybe I overlooked something but it might be worth a look.

Interesting report. Thanks for describing it in so much detail here - those details matter!

That’s always a possibility. So even though your report already includes more details than most others I see, I am going to ask if you perhaps have made any screenshots when this happened? Or played with an add-on that uploads games to hsreplay.net?
