Quite a simple deck, that really does not require much work to stall the game for eternity. Most decks in this brawl are dedicated to massive amounts of burst, or having spells constantly launched at your face. Unfortunately for them, most of those decks cannot win by turn 6, or turn 5 (if you have the coin)
For all the turns leading to turn 6, play as many copies of Armorsmith as you can. Then play Bolf Ramshield, and watch them struggle to defuse your board, or as they keep attacking your face with no success. Remember to only have one Bolf Ramshield at a time, and to keep playing him. You opponent should eventually run out of ammo.
If your opponent destroys your Armorsmith, spend a turn flooding the board with more of them before playing Bolf Ramshield again, just calculate carefully when doing this to make sure its impossible for them to have lethal.
