So I'm arguing for Boyd, and Soul is in defense of Gatrie.
First thing, Boyd has 7 movement and doesn't suffer from armor setbacks. This is huge and cannot be overlooked.
Gatrie absolutely NEEDS the 3-3 or 3-6 crown for his speed to pick up. I am going to go out and say, Haar and Oscar put these to much better use.
Boyd starts slow, but he's got instant access to a hammer and is hitting pretty hard on everything else. & once he catches up to Gatries speed, he's killing him.
Another thing worth mentioning is that boyd has access to crossbows and triangle attacking.
