>>50864755Evolving Skies has a lot of great cards of varying rarity. It's stacked with fug and eeveelutions all the way from alts arts down to full arts and vanilla V/Vmax cards. So if you're lucky enough to pull an alt you're likely to get a good one, and if not you at least get some sought after pokemon in lower rarities. Just a lot of value across the rarity board in the set.
Both Brilliant Stars and Astral Radiance have some solid rare hits, but what makes them both extra fun is the Trainer Gallery subset, which can take the place of a reverse rare in a pack. So even if you don't pull something from the main set you can still pull a Trainer Gallery card, or you can even potentially get two pulls in the same pack.
Similarly Shining Fates is theoretically pretty fun to open due to the Shiny Vault subset, which features some really nice shiny pokemon cards. The problem is that you have to commit to more expensive promotional products to get packs of it and the cards in the set are so cheap on the market that it's hard to justify not just buying them single. If you pull anything less than Charizard then you're basically in the red on your purchase. Wouldn't reccomend buying sealed products, but it can be a fun set to collect through buying the cards themselves.
