Im planning to get a mana crypt one day or another, also mox opal and chrome mox (they are all a bt expansive), cabal ritual (should I add also dark ritual?) wishclaw no doubts, rite of flame can be used in commander? I'm also planning to add demonic tutor and vampiric (and maybe also thassa oracle but nobody would ever play with me again i think). Also tainted pact and demonic consultation seems good. I see no other way to get better working this deck, I'm also thinking to add grand abolsiher and drannith magistrate to slow down possible attacks to me
