This is a stealth & bleed deck using Reunion Kamut and Recruitment Exercise to get more vampires out fast and cheap. Bleed is done using Loss, with o modifiers for stealth.
Black Hand Seraphs have acces to the A&B enhancers Tattoo Signal and Seraph's Second, allowing the same vampire to run both bloat and bleed actions in a single turn.
Watchtower: The Wolves Feed hits the table at some point to improve bleed power, after an innocuous Gehenna card like Break the Code has been played.
Tips & Tricks
The Art of Memory is a versatile modifier and provides a bit of recursion. It can be used to get a Loss, Seraph's Second or Reunion Kamut back, depending on the hand. The second
Blood Awakening can be used to improve stealth or to intercept a key action, depending on the context.
The deck should avoid combat until Watchtower: The Wolves Feed hits the table, as it has nothing else to help combat.
The Fourth Cycle is used as a last resort safety line to avoid dying from Watchtower: The Wolves Feed if too many Gehenna cards hit the table.
The Assamite version as given in example is the most common. Truth in Ink can be added along some wakes for bleed defence and No Trace for combat ends.
A common variation uses a mid capacity multi-clan Black Hand crypt with d. It looses the o stealth but can be more toolboxy and even include a decent combat module. Mark Loughman's deck from 2018 is a recent example.
Elimelech the Twice Damned can be the star of a similar construct using A and even E atop o. It looses the access to Loss but gets bounces with A and can even get Kindred Spirits if E is present enough in the crypt. Carlo Daniele's deck from 2019 is a recent example.
Pentex™ Subversion has been modified by an errata in September 2019. It does not prevent a vampire to act anymore, so it is less powerful. Its ability to disable a strong blocker is still an important aspect so it can have its place here.
