Our 3E Spell Lists and casters.
We made more use of the Descriptors (originally mainly energy types, but included Plant, Polymorph, etc) and made several of our own (Celerity, Combat - Ranged, etc). Then each type of caster was granted access to the Universal spells and a few descriptors depending upon the caster.
Eg: Hexblades: Universal, Combat - Melee, Curse. (Off the top of my head).
Some, like druid, got to choose from several descriptors. Anyway, it took Monte's Arcana Unearthed even further and made each class's spell list flavourful. Felt like different classes.
