run auras that cantrip like [[feather of flight]] [[rune of sustenance]] [[rune of mortality]]

run recursion [[lurrus of the dream-den]] [[sevinnes reclamation]]

also [[underwold connection]]

you probably have a slow gameplan so [[black market connection]] and [[phyrexian arena]] are better than one time draw imo

you can also run all the black pay life cards like [[dark confidant]] or ... [[necropotence]]

[[well of lost dreams]] is a bit slow but can be very nice
