I don't think a core set should be including landwalk against allies, or protection from self except if you were including Kookus and Keeper of Kookus. It's also worth noting that there hasn't been a common creature with protection for several years, because protection is a really overcomplicated mechanic (collection of mechanics, really) that new players find very confusing.
