The photocopy will not only be unable to copy any non-copy effects that affected the target creature, it will also be unable to copy any copy effects that it can’t see. If you take a picture of a Clone that’s copying another creature, the photocopy will just be a Clone. Fortunately for you, the Clone entering the battlefieldstill has the ability to enter as a copy of another creature, but it won’t automatically be a copy of what the original Clone was copying like a normal copy would.
