Really annoying bug, while playing Arena. This has happened to me twice during my arena run. Someone played Reska and then used Yelling Yodeler on it to steal two of my minions. After that, he used Death Growl on Reska. Death Growl spread the deathrattle effect of Reska and RUSH at the same time, so the stolen minions were able to attack in the same turn (via Rush mechanic).
This shouldn’t have happened and it cost me 2 losses in Arena. I’m really disappointed.
Two of your opponents had Reska, Yodeler, and Death Growl?
Testing that on my side it doesn’t give my minions rush
Playing reska, yelling yodeler, death growl, no minion is given rush
I’m assuming you missed something, like your own minions actually having rush before being stolen
If it’s not a typo, there’s a clue in the fact that you said that death growl gave rush to the stolen minionS. Play Yelling Yodeler on Reska and both minions will be on her right. Play Death Growl on Reska and it spreads her deathrattle to adjacent minions only, it won’t spread to the second stolen minion. So if both minions had rush in the end, it’s not from death growl
