Antimagic field vs Artifacts

[Dr A Gon]

In 2E rules as written, artifact rules say "artifacts and other magic items" so we know they're magic items. Antimagic field says it shuts down magic items. So, 2e antimagic appears to suppress an artifact. 1E specifically said it doesn't.

Now I have a problem with this.

Certain artifacts by design are supposed to have huge drawbacks - example the deck of many things. If we can turn them off with anti-magic, this gives us a way to exploit an artifact.

I'm imagining an item, maybe a box you put the item to be suppressed in, to assist with maintaining or sustaining antimagic fields. And now I'm wondering how a magic item makes an anti-magic field without turning itself off.

Spells of a higher level than the antimagic field overcome its effects, and can even be cast by a creature within the field.

Magically created creatures (Maybe intelligent item's intelligence too) function normally within an antimagic field.

Then, what's artifact's unique unbreakability spell level?

This part is important, especially non-intelligent item's.
