Interesting bug/exploit

Just had a bunch of battleground minions played against me in duels? They all seemingly cost 0 mana as well. ??? (since you can’t post links I had to put some spaces)

I got a zero-cost Override Drill in my face 1st round of 1st battle in duels. Great way to start a run.

Well done, Blizzard! :100:

Opponent’s name was qBjhyCDQSd which tells a lot…

Also, the run is now broken after two additional matches followed by break. Cannot start a new battle anymore. Ranked is playable still.

In ranked Velarok is bugged. I played a spell from another class and nothing happened.

[Hearthstone] Velarok Windblade was unintentionally reverted to its prior transformation requirement (3 cards from another class).
