If there are any non-gold cards in either graveyard Assire causing problems is unusual. What exactly happens, when she does that? Can you continue the game, or does it freeze? Did you press a specific button that might have caused that issue?
Not sure what's causing it, I don't push anything besides A to play her. The card just hovers over the board as if it was waiting for me to make a selection in my graveyard, but it doesn't show me anything. I can still look at my cards and graveyard like normal but Assire only gets played then timer runs out and the game continues like normal.
