I really love this deck. I have a Nebuchadnezzar deck that revolves around making my opponent top deck and then steal from their graveyard or field. I also do some clone stuff. I recommend some steal cards as well cause they fit in the style of playing your opponents cards. Control Magic, Bribery , Treachery, and Expropriate are all wonderful cards that fit in the style of playing your opponent cards. you also can include Copy Artifact as a nice way to get more mana so you can use your commander ability more often.

Haha thanks for the suggestions! I've opted to replace Control Magic effects with removal for now as reanimating the corpses with my commander achieves pretty much the same thing :p I'm considering Take Possession, Volition Reins or Dragonlord Silumgar to steal PWs though!

Expropriate is definitely worth a slot, I just don't use it cause it's not very exciting for me. Same reason I don't run Consecrated Sphinx.

Blessed Reincarnation is two-fold, it's removal for something you might want gone as opposed to in play on your board, and it also forces a creature out of someone's library that you can then steal at your leisure.
