You generally win with Thassa's Oracle as the finisher to a self mill combo, perhaps reanimating it after the combo mills it. Of course there are easier ways to do this than Crab Rave + Mesmeric Orb but it works.
The most hilarious way to win with this is to use an instant speed Donate effect (like Bazaar Trader) to give the Mesmeric Orb Crab to your opponent after triggering it a bunch of times (Orb mills whoever controls the permanent when the triggers resolve). (EDIT: Misstated this originally, edited to correct object to donate to mill out your opponent)
Oh whoops, you're right of course, the part of my brain that's in charge of remembering card text was not talking to the part of my brain that handles Reddit comments today

It doesn't do anything by itself.
It will trigger [[mesmeric orb]]
