I’m a numerologist first and foremost, so I usually read with the Rider-Waite deck. With Rider-Waite, reversals matter to me - a lot of meanings land better when a card is flipped.
I also like that a deck with more variation has more... language, I guess. Reversals practically double the symbolic options, so readings feel more layered and nuanced.
What I appreciate is how flexible reversals are. A generally positive card turned upside down can point to something weaker, blocked, or hollow - like the energy is still there but not fully landing. Conversely, hard cards can be softened, or sometimes show consequences getting more intense or drawn out.
For me, the whole system just feels intuitive and naturally expands how many ways you can read a spread without forcing anything.
