Look like I'm a little late to the party, and a lot of great ideas have been posted here!
Mine is a little out there. It would involve keeping the deck Red/Black and madness themed, but instead of being vampire heavy, it would be spell heavy, and based around
Thermo-Alchemist +
Prophetic Ravings.
Having the option to ether tap for Damage or tap to loot is incredibly powerful, and since he's an 0/3 you aren't losing a big threat. He also uptaps every instant and sorcery spell, making
Fiery Temper insanely good (Tap Therm-alchemist, discard and cast
Fiery Temper, draw a card, untap
Thermo-alchemist). It isn't exactly on theme with vampires, but it's something to think about. in a spell heavy Red/Black deck, Alchemist +
Prophetic ravings could chain into some serious card advantage.
of course the exact list would be up to you, but in my head it would look something like this:
//Land
11
Swamp11
Mountain//Creatures
4
Thermo-Alchemist4
Insolent Neonate4
Olivia's Dragoon2
Bloodmad Vampire2
Bloodhall Priest//Spells
2
Alchemist's Greeting2 Avacyn's Judgement
4
Alms in the Vein
4
Fiery Temper4
Murderous Compulsion2
Lightning Axe//Other
4
Prophetic RavingsWith the major win conditions being the Madness Vampires and
Alms in the Vein (usually a card I don't recommend, but when you can always cast it for 1 and typically draw an extra card off it, it gets way better). I imagine you already have a huge percentage of this deck and it should cost WAY less than $65. Swapping out a couple
Alchemist's Greeting or
Murderous Compulsion for
Abandon Reason or
Distemper of the Blood could tune for how you and your father play.
Just something to think about. Enjoy
