This basically plays like a slower aggro deck when it doesn't work and a reanimator deck when it does. Cast a few vamps to deal with any aggro and cause some damage of your own until you get
Anje Falkenrath
. Then use him to dump any cards with Madness (plus any vampires if
Falkenrath Gorger
is on the board, which he should be). After a decent amount of bodies and a
Malakir Bloodwitch
or two are in your graveyard, bring them all back with
Patriarch's Bidding
, kill everyone with life loss, then finish any survivors with an alpha swing next turn.
Even without
Patriarch's Bidding
, the combination of having
Anje Falkenrath
and
Falkenrath Gorger
enables you to instantly drop vampires at any time. Having an instant
Gatekeeper of Malakir
or
Captivating Vampire
can easily and unexpectedly swing the tide of a battle into your favor.
