This sounds like it was designed for Kōhaku Narukami and his Geist weakness Weeping Yurei. Although an annoying weakness if drawn at the wrong moment, you can pretty much control when the thing attacks you with a Kōhaku deck, and assuming you were investigating anyway Oculus Mortuum helps you getting the clue and at the same time stinging the little hit-and-runner. I see this as a true blessing regarding its keywords and the fact that the last damage will interrupt and negate the attack.
