How to evaluate it
Judge Necro Mastery by the job it fills in your current deck, the fights ahead, and whether its 2 energy competes with a more urgent play. A card being rare does not make it an automatic pick. Check its class guides and the current patch notes before treating any single-card rating as universal.
