Forum:Unaffected by card effects VS Cannot be destroyed by battle

My friend had Dark Magician Dragon Knight/Eternal Soul combo (spells/traps/monsters unaffected by card effects) on the field. I have several cards that cannot be destroyed by battle. These effects (obviously) aren't negated, but I know a monster that is unaffected can attack even with cards like SoRL on the field so... that's my question. Can he destroy cards by battle that cannot be destroyed by battle if his cards are unaffected by card effects.
