everyone has a background, and if you arent proud of yours, well, we all have our secrets, myself included
Armies with a lot of Codices would have lots of concepts to choose from
First, the deck starts with discard outlets that also draw cards including blood tokens (Voldaren Epicure, Vampire's Kiss) and faithless looting to provide quick ways to enable madness
Notably, this triggers off of any discard, so cards like Faithless Looting and Cathartic Reunion become much stronger
This means that in every two-color combination, you should be able to find a least six really strong MDFCs, and if you reach down into the "often play" category, you should be able to find eight or nine that are worth putting in your deck
