Interesting. Gotta say I love it when someone puts a neat card like Dream Salvage to good use. +1

I just play tested this against my Affinity deck & it lost 1-2 (Granted I didn't board for either deck after first round, but that was also the round your deck won). Considering how quickly I empty my hand, it's a pretty decent match up. However, I'd add some board wipes & spot removal for the more aggro oriented match ups. I'd put Dream Salvage (Being a dead card late game) & Ashiok, Nightmare Weaver (Being defenseless & in some cases useless) in the side board for, say, Damnation or maybe Drown in Sorrow , & Dismember . & seeing as you're pressuring aggro players to put what they don't want to discard on the field all at once, you'll get a nice bulk of value out of your board wipes. I'd also probably consider some counter spells for the deck as well such as Remand , Spell Snare , Mana Leak , &/or Spell Pierce to slow them down even more so. Just a little food for thought. But all & all I like this. +1

Maybe some Creeping Tar Pit

I really like some of the ideas you're playing with here although I do believe that you're a little too focused on the discard side of things and don't seem to be thinking about defence at all.

More specifically, why aren't you running any creature control main deck? Cards like Ensnaring Bridge , Bitterblossom , or even Darkblast are needed for when you don't draw into what you want first turn and a creature manages to slip in. What happens when an affinity player dumps their hand first or second turn? Currently, you're counting solely on 2x Liliana of the Veil which means you have a 22.1% chance of getting her in your opening hand, 25.1% chance of her on your second turn, and only 28% chance by third turn when you could cast her. With a format that is so creature heavy, I just don't like those odds. Cards like the bridge are essential to keep you safe, and to keep your Lilly safe so she can make your opponent discard every turn and shape the game to your favour.

Since you're not running Dakmor Salvage + Raven's Crime you may want to lose that discard spell and free up room for control. I know our 8Rack decks want to ideally prevent threats from even hitting the board, but a Plan B is essential, in my mind.
