add the urza's lands? and add karn, silver golem

add zombie master and urborg, tomb of yawgmoth? and maybe cabal coffers

I don't think id use cowardice and id stay with chasm skulker

jace, memory adept and traumatize are a few of my favorite blue mill cards

cathar's crusade is dangerous in a token deck

lmao funniest theme you have done yet

or maybe vineweft

id add banishing light for some removal and archangel of thune is a cool card but its a bit pricey

haunting echoes can be a game ender in u/b mill

add some tutors? and some unleashed creatures like exava, rakdos blood witch and rakdos cackler

swap doom blade for go for the throat and add 2 nykthos, shrine to nyx

add supreme verdict? wrath of god? banishing light? oblivion ring? silence? render silent?

add vorel of the hullclade?

add serpent generator?

maybe drop chain lightning for bonfire of the damned and u could drop a few of your 0 cost artifact creatures to get an alloy myr and opaline unicorn to help mana fix

I wouldn't use exhume

crypt of agadeem is another good land

add some more tutors? maybe add urborg, tomb of yawgmoth so your coffers will be swamps to? and with all the mana ramp killing wave and sorin markov might be good

love the new nissa in here that card is a beast. overwhelming stampede might be a good addition. maybe some more x cost creatures like krakilin or vastwood hydra

if you run it as mostly black look through my vamp edh deck it has a lot of the staples for a black edh
