Couldn't sleep tonight, so I broke out Photoshop and started playing.
I tried my best to eliminate the Island from the image, but without good scan it was difficult to do. The perspective and especially the glare made it difficult. Below is best I could manage.
Observations:
The other card is skewed down and to the left of where it should be.
The word Artifact is clear.
Unfortunately there is no card name visible, where the card name should be.
There are 4 lines of text. The 4th line is short.
I'm pretty sure the one blotch is a tap symbol.
Conclusion:
I looked through every artifact in Tempest, as well as Exodus and Stronghold (in case this came from a precon), and there are no cards that match this text layout exactly. However, the card could be French (Artefact).
3 possibilities:
It's not from Tempest block
It's French (and all my words are wrong)
It's an English artifact with text that was changed before the final print
