Yes, it's a miscut. Does it add more value, unfortunately that's up to an individual's preference. This miscut can also be mistake as an off-center. It seems that Exodus miscuts are prominent across the board (commons to rares). Whether this card is worth more or less is up to you or whoever you're trying to trade/sell it too. I would let the person you're trading to know if you haven't already. They might not be into miscuts at all.

Best of luck.

I'd be looking for the Foil Archangel if you see anything in my TL. Feel free to message me!

Worth a mention, if you don't need the deck asap, wait for BfZ to come out. They reprinted Sylvan Scrying.
