Card rarity is a general indicator of how rare and/or valuable a card can be. There are 8 possible rarities that a card can be:
- Common (C) (7 or 8 per booster pack)
- Uncommon (U) (3 per booster pack)
- Rare (R) (1 per booster pack)
- Super Rare (SR) (first added in High Magic; 1 in 4.5 packs=8 per booster box of 36 packs; foiled until Seaquestria & Beyond)
- Ultra Rare (UR) (2.77 (in Premiere), 3.27 (in Canterlot Nights, The Crystal Games, and Absolute Discord), or 4.00 (Equestrian Odysseys, High Magic, Marks in Time, Defenders of Equestria, and Seaquestria & Beyond) per booster box; always foiled until Seaquestria & Beyond)
- Royal Rare (RR) (first added in High Magic; 0.33 per booster box=1 per 3 booster boxes; always foiled until Seaquestria & Beyond; alternate-art with no black borders versions of some Ultra Rare cards)
- Fixed (F) (only found in select products, where they can always be found, such as Theme Decks; usually not foiled)
- Promotional (P) (only found in select products or from special events; always foiled until Seaquestria & Beyond; may be alternate-art versions of non-promo cards or can be promo-exclusive with no other version)
The rarity of a card can be found on the bottom right of a card to the right of its card number. (On Problem cards, the card number/rarity information is located on the top or bottom of the card, or on the right or left side if you are reading it from a player's perspective.)
A foiled card will usually not have the card's non-foiled rarity shown, instead replacing it with the ƒ symbol. The exceptions for this occurrence are Super Rare, Ultra Rare, and Royal Rare cards (which were always foiled until Seaquestria & Beyond, and will display the regular SR, UR, or RR instead of the ƒ symbol) and Promotional cards (which display both the P and the ƒ symbol).
