Card not found, on the other hand, is the basis for a deck in Modern (its namesake actually) and played in Legacy Storm decks (maybe Vintage as well, I dont know the format enough to say)
If your plan involves milling yourself, though, I can see it being useful, since it can be cast if you mill it over yourself
For example, I wouldnt replace Marang River Regent one-to-one with Eddymurk Crab because the Regent isnt just a big creature, its also a card-draw spell
