I had 3 creatures on the board, played Dancing with Devils, summoned a Raging Goblin and a Bloodcrazed vampire. I attacked with all and all that was left on my board was the Raging Goblin and their Death’s Shadow. At the end of my turn Dancing with Devils popped up like it was being used but then it disappeared from my hand and no creatures appeared. On my opponent’s turn they played soulsever lich and attacked while i blocked. At the end of their turn they Dancing with Devils did not activate and I was left with no creatures.
