6$ Black Dis-cardio (Casual) [Revision 5]

This is a budget (less than 10$) black deck, based on card discard. It aims to make opponent discard cards early and keep applying the discard pressure until we get complete control of the board.
It is based around:
-Discard creatures (Acquisitions Expert, Elderfang Disciple, Augur of Skulls), while squeezing out more value from Acquisitions Expert, since we often have more than one creatures in our party.
-Make opponent lose life through discard/empty hand using Fell Specter, Davriel, Rogue Shadowmage and Raiders' Wake.
-Reanimation of our creatures through Nightmare Shepherd, Malakir Rebirth // Malakir Mire for re-discard.
-Card drawing through sacrificing weak creatures after use, with Ayara, First of Locthwain, Village Rites.
-Inscription of Ruin is a multifunctional spell, doing 3 relevant abilities with one card!
Sideboard contains some removal spells, when the opponent manages to put some strong threats in board before we manage to make him discard. However, I feel more for the discard-only concept for now.
Maybeboard contains popular options for black discard decks.
Suggestions are always welcome!
