I actually agree with linking on that. But what would win a tree, or a machine-gunning rocket firing, metal plated boss?!
But I think the pairings should be like this: Mourning wood vs Everscream Pumpking vs Santank Pumpking and Mourning wood vs ice queen
To be honest Pumpking's agility will only get so far before someone lines up it's cephalothorax in their sights and "BOOM HEADSHOT!"
