The focus of this deck is just to out sustain the enemy with some buffed up taunts and since this deck has no natural way to heal yourself it centers more on Armor than health. To get a lot of armor in an instant you need to to have at least 9 Mana (8 with Coin... duh) and "Rocket Boots" + "Sweeping Strikes" + "Vicious Scraphound" + "Bronze Gatekeeper" (double buffed with "Into the Fray").
First you play "Bronze Gatekeeper" and then just mash the rest on to it. Then you attack a minion that has adjacent Minions on both sides and hope that it survives till your next turn so that it may attack again. Since the "Bronze Gatekeeper" should be buffed up to 7 Attack you should get up to 21 Armor with one Attack.
