I was thinking about single target protection spells to add for an aura commander deck, and it came to my mind that it was weird that no hexproof-granting (not just until end of turn) aura with flash existed, so I made one. Maybe the cost is too efficient at just 1, but 2 mana seemed too much for how specific this is. And although it's quite simple to grasp, it's a rare for the sheer efficiency alone, although maybe it could be a fine addition to some peasant cubes.
Probably too cheap given that it's a permanent, but with wizards printing shit like they do who knows anymore. The fact that's it's specific just means it's only going to be played in a few deck types, but in those deck types it's going to be very powerful.
