I played to hastily and threw out the savage roar BEFORE my force of nature. Only realizing this after playing force of nature. So I missed lethal, and was forced to send my tree ents to his enraged warrior legendary. It got even more dire when he faceless manipulated my Rag, and his killed mine.
But the RNG Hearthstone gods felt sorry for me and top decked me a tinkmaster and favored me some more with at 1/1 because I had no way to deal with a 5/5 at this point. The game went on for turns as we both exusted our legendaries and were throwing oozes and golumns and playing black knights with no taunts.
I ended up winning, but lesson learned. Play slow, and make sure force of nature first!
