Seriously honest legitimate question here.
For example, one could argue that, say, Captain Marvel (DC) beats Darkseid because Darkseid's lost to Superman and Orion. But another could argue it wouldn't be that easy since Darkseid's no-sold attacks from Supergirl and Lobo (separately, but yeah).
Both happened. Both are valid. But trying to get people to agree is fruitless. In some cases, the defeated feel like winners (I won't name names, cause of board rules).
So my question is, why do you personally battleboard?
