less-played cards for Savra?

I am trying to build a Savra deck, but I am sick of always seeing the same cards in every deck. For this deck, I am trying to stay away from the "auto-includes" that are in every other deck. For example, instead of [[BloodGhast]], maybe trying [[Brood of Cockroaches]]. [[Soldevi Adnate]] instead of [[Viscera Seer]]. Things like that. Anyone have recommendations?

Also, just g/b obscure cards general. My contribution? [[Grim Feast]]. This should negate Savra's life tax very well.
