@ll01 You can get away with no Fiendsmith's Tract and no Fabled Lurrie as long as you have the mandatory Fiendsmith's Requiem, because Requiem can special summon Fiendsmith Engraver from the hand or deck. Fiendsmith's Sanct is a good replacement for Tract because it's searchable off Engraver's effect and produces a light fiend token for Requiem. Also, Lacrima the Crimson Tears and Fiendsmith in Paradise are not mandatory, but they help out a lot for grind games, and in the latter case, removal.
