Maybe you can try Grafdigger's Cage and/or Surgical Extraction in the sideboard as your graveyard hate, I think Relic of Progenitus is not efficient enough because you'll need to keep leaving up mana.
Other sideboard options include: Counterspell, Ethersworn Canonist, Abrupt Decay, Leovold, Emissary of Trest, and more Flusterstorm and Swords to Plowshares.
Good luck!
