The order of pick up for cards is Numb>Meth Head>Battle Lust>Damage Resistance cards>Melee Damage Cards>everything else.
The whole point of the build is to get more temp health than damage taken. With all cards that give damage resistance, a melee weapon, temp health and playing as Holly you can get up to 65% damage resistance not even taking in account Scar Tissue. The required card to make a melee build to work from the get go is Meth Head or another melee speed card, Damage cards are only needed for veteran difficulty or higher or when you want to smack a special. Down in Front is only when you don't want take friendly fire, can be replaced for anything, ignore the pain can be replaced too. The preferred melee weapon is machete or baseball bat for its cleave, until you grab Mean Drunk at which point you can pick any melee you want.
It is not recommended to play this deck if you don't get Holly due to her stamina regen and damage reduction.
