Hi again,
Looking at your mana base, you have slightly more green mana sources, compared with black ones, while the statistics say the opposite. Maybe you should correct this.
Cards I will cut:
Sanguine Bond +
Exquisite Blood (it's a 10 mana total combo that otherwise doesn't interact at all with your deck, I'd rather use these slots to increase sinergy)
Mortuary (there are better ways to
recycle your dudes)
Parallel Lives (you don't create that much tokens to justify it)
Atarka's Command,
Golgari Charm,
Rakdos Charm,
Jund Charm (mostly unrelevant, just play more sweepers instead)
Lavalanche (it only target one player and is very mana-expensive,
Torment of Hailfire is enough and can be your win condition when reaching infinite mana too)
Liliana Vess (it's basically a 5 mana
Vampiric Tutor, next turn you'll always plus her or she will die and that'll be mostly unrelevant, then you could tutor again but that'll be pretty slow).
I can't stay more time online, if you want more advises, I could write more later.
Bye.
