Playing with the Wicked Wolf in a "Food" oriented deck, Greg had no enemies out so, instead, my wolf fought the next creature IN MY HAND. Then, when I finally cast the creature on the battlefield, it fought it there and killed it.
After that, it stopped attacking my creatures.
In order to help us, please provide the following information (you can PM me the answer if you prefer, or send it to Customer Support in-game):
Which card?
