You should consider the B/R Reanimator version. You already use much of their cards (petal lotus, Chancellor, Sire), and the only cards you really need to add are pretty cheap :
Dark Ritual,
Faithless Looting,
Animate dead.
What you lose in deck manipulation (
ponder,
preordain), you gain in speed and explosivity, with potentially insane T1.
Of course you lose power because of the budget option (no
Griselbrand,
Unmask, Mox, or fecth/biland) but I think a B/R budget version can still perfom really well
