It’s happened in my last two games, but when 2 of these are on the field at the same time, one or more minions will someone 5 or 6 Sky Pirates instead of 2. There were not any minions, trinkets or quests to explain it. There was a Rivendare in play at the start of this once or twice, but it summoned the extra minions even after he died
were dragons in your game?
