I built this one for the Pauper Challenge and took it to 6th place! It may have gotten top 4 if my only opponent I lost to hadn't dropped after the 3rd round.
It's build around
Bear Arms (inspiring the name) which combos incredibly well with
Bloodnurse to make as many bats as you have power available. It also works very well with
Lazy Firemane by making it an instantly huge beater. The rest of the deck is mostly efficient aggressive units and interaction to fill things out, as well as
Stonescar Outfitter to give it that extra punch when the deck goes wide.
