Ok, I'll buy that provided one thing. Prove to me that magic circle doesn't allow a saving throw for a creature moving into its area. The spell allows a saving throw, and normally, any time an area effect lists a saving throw, any creature within the area gets to make a save. I don't see anything within the magic circle description that contradicts that, but I might be missing something.
I think I found the answer. However, it may not be the one you might expect.
Magic circle has a range of "touch" and an area of "10-ft.-radius emanation from touched creature." Although a debated point itself, most people will agree that a targeted spell is one with a Target line. This spell does not have that, so it is not Targeted. It does, however, have a saving throw as you've said: "Will negates (harmless)." Let's look up "(harmless)":

(harmless)
The spell is usually beneficial, not harmful, but a targeted creature can attempt a saving throw if it desires.
A targeted creature can attempt a saving throw. Lemma 1: By simple logical negation, that implies that non-targeted creatures cannot. We've already shown that this spell has no targeted creatures, and therefore no one gets a save.
That can't be right because it would assume a glaring error in the book. Instead, it makes more sense to reconsider the idea of what is targeted. The closest approximation of a target in this example (based on the spell stat block) is the creature touched. Lemma 2: That means that only the creature touched gets a save, if he desires.
Should you decide, however, that Lemma 2 is false, the only alternate conclusion is that everyone inside the magic circle is a target. I don't think that's correct, however, because targeting has a few other quirks not readily handled by this. For instance, if someone's invisible, are they or are they not 'targeted' by the magic circle? To target something, you must generally see them. The targeting of the creature touched is inherently handled, so there are no other confusing situations with that interpretation. This lends credence to the interpretation that only the person touched gets a save.
Admittedly, this is a very confusing scenario. Please let me know if this makes sense, or not.
