Rough // Tumble seems good, but would you play it mainboard? Dread of Night seems better from the sideboard.

Ben Friendman posted an article on Grixis Delver, specifically about his love for Snapcaster Mage and also about the new turbo Angler build:

The True-Name Nemesis build seems interesting. He says he would cut 'Goyf for either Angler or Strix and I'm leaning towards the first option myself.
