Whenever I get the quest for "Attack with 45 Creatures", my heart sinks. I try to complete this quest and it seems whenever I am about to attack with any significant number of creatures, my opponent just snap concedes. It turns into trying to attack with enough creatures to not win which doesn't seem like the intent. I don't have a suggestion except to just remove this quest because of the interaction with the likelihood of an opponent conceding when you are about to make significant progress.
