This Incarnation was originally much worse than the others (Brawn, Anger, Wonder, Valor) because it was printed in Judgment, a set where green and white got disproportionately many cards and good cards, and black got fewer and worse cards (to make up for the preceding set Torment being the other way around). So I think in a kind of "ideal" core set like you're going for here, black would get a better Incarnation than this; perhaps a take on Archetype of Finality.
