"Weak cards"

Boseiju: Enters tapped
Thawing glaciers: REALLY slow
Vesuva: Also slow

Blood artist: only good in LD loops
Bloodghast: pretty much only functions in conjunction with skullclamp
Fallen angel: Should be bloodthrone vampire

Pawn of ulamog: to much self sacrifices? only good with blood artist
Reassembling skeleton: see Bloodghast

Corpse Dance: kind of bad without a sac outlet...
Hatred: Oneshot effects are dangerous
Moonlight bargain: Just keeps its place due to being a pet-card of mine...

Deathcloud: is it worth it? ruining my board?
Living death: Deck is reliant on getting this one off, without it I should be able to build the deck in another way entirely
Promise of Power: Expensive one-shot at draw... worth it?
Rise: LD #2
Syphon mind: opponent's are occasionally hellbent, bad politics
Victimize: really "cute"

Altar of dementia: Fuels the LD loop
Blasting station: "win more" with LD loops?
