Maybe consider "
Karlov of the ghost council" for your commander to add a lot of control.
If you do so then
Detention sphere can be switched to a
simple stasis snare since it's commander it won't change much
"the
staff of the death magus",
You should really get "open the vault" as of right now you have 21 possible crucial elements you could bring back.
"
Test of endurance"
"
aetherflux reservoir" is a much more reliable way to
deal damage than easily removable creatures like "
serra avatar" and "
minion of the wastes" that could anyways get blocked by a poor 1/1 saproling if you see what I mean, usually in commanger big evident threats don't tend to stay long on the board ; "
Servant of tymaret" is a lot more
humble and resilient and blocks just as well, as long as you have 3 mana to spare ofc.
I would add a "
Phyrexian arena" is kinda like "
dark tutelage" but in a lot better i would argue, you end up paying less life and you don't reveal anything. But if you feel like you can't have both take the first one.
Drana's emissary feels a bit clunky because it is so slow, for the amount of her ability to matter, on the other hand it's not a meaningfull target at all and is therefore a sneaky way to lower your opponents life total... but will it die in the smallest board wipe ? yes definitely
the
thrull parasite feels like a
dead draw, i would rather have "
in garruk's wake"
Definitely add a little bit of protection like "
eerie interlude" or "
ghostway" ...

Chant of vitu ghazi if you tend to get killed in 1 wave of huge minions
1 or 2 fetch ... keep in mind Black is known to help you get any card from your library with the tutors, and you should abuse this as much as possible.
