So am I jumping to conclusions? A little. Is that something MTGMultiverse denizens would do? Highly likely. Would I trust any jewelry-makers from Phyrexia? Absolutely not.
Is this a joke? Cause this doesn’t look like an exhibition of the latest in merfolk fashion. It looks to me like that giant mollusk is trying to eat that merperson. They aren’t wearing a new necklace, and the mollusk doesn’t merely want a hug.
