Hey there,
The astrological, cosmic, and mythological aspects in the Specter Cosmos Tarot make it sound aesthetically stunning. However, there are other factors than visual appeal to think about when reading tarot.
The visual appeal of a deck is nice, but the most important thing is the quality of your connection with the cards. The artwork of themed decks like this one can take precedence over the clarity and depth of the messages on occasion. I can see it being ideal for those who have a deep interest in mythology and space. Although this deck is more of a collectible than anything else, it's worth considering if you're seeking something with powerful, obvious, and easily interpretable meaning.
Whether or not the deck speaks to you personally is what matters most. Good for you if it does! If that isn't the case, you can find a wide variety of other decks to choose from.
It is merely something to think about! 🌌
