Well of course the extra monster zone is there, they're using modern rules. He can't spam it anyway, it's once per turn so it's not going to affect him that much. Unless you're referring to him not having the pendulum zones/extra spell and trap zones which again, is really not going to affect him that much. Rule 5, they're using rule 5 okay, it basically doesn't affect anybody in any major way so it's the fairest for everyone involved.
