Very simple brute-force deck: get out your beefy bois, smash face. It is about as subtle as a sledgehammer to the face. Luckily, it is also about as effective as a sledgehammer to the face.
I might drop one Land of the Free for another kill card and I have considered pitching the Half-Tracks for 3rd Marine Regiments to up the beef quota, but right now this is a pretty solid deck - I mean, it did get me to Field Marshall. Get out your 4th Marines and smash face, because there are really very few answers that many decks have when a 4th Marines is operating with zero operating cost. You can regularly swing the 4th Marines out into the front line on turn 3 (turn 2 War Machine, turn 3 4th/Land of the Free) and then there's this 6/6 slab of beef just sitting there and your opponent either gets smashed or burns multiple cards to kill it. And then you do it again. And again.
