Main Board:
Skymarcher Aspirant: Hard hitting one drop that is often flying over for damage by turn 5.
Duskborne Skymarcher: Evasive One Drop that can also help other vampires trade/attack more favorably
Adanto Vanguard: Good removal/board wipe hedge that can aggressively attack for Mavrein Fein
Legion Lieutenant: The only black card in the deck, and lord to our vampires
Martyr of Dusk: Good removal/board wipe hedge that can aggressively attack for Mavrein Fein
Mavren Fein, Dusk Apostle: Early/Mid Game token producer to help us go wide
Metallic Mimic: Our lesser lord, but turn 2 priority cast. Will happily attack with it turn 3 with Mavren Fein, Dusk Apostle if necessary
Legion's Landing: One Drop and Mid/Late Game Token producer, also a functional third or fourth land drop for us and really awesome when it's popping out 2/2 Lifelinkers every turn
Radiant Destiny: Awesome Anthem effect for all our vampire weenies
Baffling End: The worse White Fatal Push that's easier to cast for our deck and counts towards Ascend
