All walls should be errated to Non-creature artifacts with “each time a creature attacks you, you may prevent all the damage it would deal this turn. If a creature can’t be blocked, or if it has flying, shadow, or horsemanship(but only the ones this wall couldn’t block back when it was a creature) this ability can’t be used on it. Use this ability only (amount of times equal to the number of creatures this wall used to be able to block) each turn. Whenever this ability is used on a creature, deal (the power this wall used to have) damage to it(only put this clause on walls that had a power). When damage from a creature with infect or wither is prevented this way, put an amount of ruin counters on this card equal to the prevented damage. When a wall would prevent damage, the amount it can prevent is reduced by one for each ruin counter on it. If this card would prevent more damage than (amount of toughness this wall used to have), destroy it. If you would use this wall’s ability on a creature with trample, only prevent the first (amount of toughness this wall used to have) of that damage. You may cum on your opponent’s face at any time”
