Died After Killing Demon Hunter in Tavern Brawl

I was a playing a Druid Deck against a Demon Hunter in the Outlandish Burndown Tavern Brawl. I was at around 20 health or so when I dealt exact lethal to the Demon Hunter (using my hero power). Instead of exploding, the Demon Hunter’s Portrait started glowing green around the edges and flipped around, and I died instantly. I got the “Defeat” message and when I cued up for the next game I had the Demon Hunter’s deck. This was extremely frustrating, since I had been winning with the Druid Deck and then it was gone for no reason.
