How do you know a Pokemon's rarity? Is it related to "EVO"?
EDIT: Ah, EVO means the level the card will evolve. I also see tiny marks on the cards in the shop that might be rarity but I don't see those marks on my own cards or on opposing cards.
I figured out the symbols, but actually yeah that's a good place to look to see the difference. There are circles/diamonds next to Pokemon names but I just had a bunch of common cards that looked the same so I didn't notice anything.
