If you're going first, don't change anything. If you're going second, change the mill cards for the side deck cards and pray for your opponent to be playing a casual enough deck to not murder you in seconds.
If you're going first, your strat is to summon Soul-Absorbing Bone Tower as soon as possible and start summoning as many monsters as you can. Since all your monsters are zombies, they'll all trigger Bone Tower, milling cards from your opponent's deck until they have none, at wich point you've won.
