It could be called a bit of a stretch, but whereas
Earth is an element that holds on to and protects its permanents,
Air could be one that freely gives them away, or at least copies.
Now, if the opponent were to simply receive permanents, that wouldn't exactly be a hindrance, and that would be seen more of an altruistic act. I think we all would know where that would typically fall under.
Aurorae result from the combination of light with substances in the sky, which is why I find it fitting to put under the element of
. It could've also fallen under
Light, but its cards often display the mechanics of ignoring what others do and shining through.
Light (along with
Aether) is also one of those quanta-investing elements, that is to say, it tends to have cards which are a little more expensive, but can be devastating once out.
Air cards tend to be a little more on the
lighter side, and therefore it could actually be detrimental for an opponent to receive cheaper permanents.
