these "themes" are often called "cycles". you can look them up on several pages, including mtg-salvation wiki ( for example on every editions/sets main page)
there are also mirrored pairs (soul of harves -
harvester of souls) and other types of cycles ( common, uncommon, rare small cycle (splicers) for example)
Not all cycles fall into your category though, like random common/uncommon cycles ( clan specific creatures from KTK for example)
