The singles market has changed significantly since I last looked at this deck. The Modern metagame is also quite different. So, I made several changes and improvements based on these developments. Keeping the list under $100 USD remains the primary design goal.
A much more intelligent and effective sideboard is now listed. The reprinting of Inquisition of Kozilek in Conspiracy: Take the Crown and Modern Masters 2017 Edition has made the card fall to under $10 USD. That allows us to run it in place of Duress. Relic of Progenitus is cheap now, too, so we can play it. Damping Matrix is our best answer for Affinity, even though it is slow. Dark Betrayal is a budget Fatal Push for Death's Shadow aggro decks, and it also hits Gurmag Angler. I removed the ineffective Haunted Fengraf for Ghost Quarter and sideboarded another copy as answers to Tron variants (Eldrazi and otherwise). Drown in Sorrow is a sweeper against aggro lists (including Affinity) and tokens.
The mainboard now includes Drana, Liberator of Malakir along with a playset of Shadow Alley Denizen. I adjusted some creature numbers, too, and I went down slightly on removal spells since there were too many for an aggro deck. I cut Go for the Throat in favor of a pair of Dismember, which is now cheap enough to play. The list is more aggressive and hopefully a bit more stable in this configuration. A mix of aggressive, evasive creatures and efficient, synergistic removal spells should make this a solid budget list for players looking to compete in Modern while playing a tribal strategy.
Finally, there is Aether Revolt's Gifted Aetherborn to consider. It is hard to imagine a better two-mana Vampire. It seems correct to run some number of this card, but I am unsure of which cards to cut for it. Sign in Blood seems a likely candidate, but a card this efficient really seems to want to be played as a 4-of. I'll have to playtest and consider.
