See Hunter's Prowess. First, I would like to state the effect of this aura should be the lowest concern at this time. The ability was just a top-down concept to toss onto the card, so that the card subsequently qualifies as a card. With that out of the way, I took another look at the greater concept of Identity. Hunter's Prowess was a lot of extra work for very low relevance. So, perhaps identity shouldn't be unique. Are people different? Yes, but humans (and presumably fictional humanoid creatures) often fall into tropes and behaviors that are archetypical of some role.

Flavorwise, this iteration of identity allows a new creature to take on an identity that has been.

Mechanically, this was inspired to increase the usefulness of auras to make them more comparable to equipment. Equipment can stick around, so the need was to make a way for enchantments to be reusable. On one hand, this was makes permanently removing an aura significantly harder to do, however, the decision of what can be enchanted is limited to one early phase, which I would expect to be a respectable limiter. I sought this route soley for the vanity of not using Rancor's clause.

That reminder text looks about one or two lines longer than it needs to be:

> When this permanent is put into a graveyard, exile it. [At the beginning of|During] your upkeep, you may cast this card from exile [if exiled this way].

Identity seems not a perfect name since it can mean other things. "Profession"? "Lasting ideal"?

It does feel like returning to hand might be simpler. Maybe have a mana cost to activate the save-from-graveyard ability, so the opponent does have more chances to interact with it.
