My Little Pony: Collectible Card Game – Canterlot Nights

Canterlot Nights is the name of the second set released for the My Little Pony Collectible Card Game.

American release: May 23, 2014 European release: 5 June 2014

204 unique cards were released as part of the main set:

10 Mane Characters, 
100 Friends, 
30 Events, 
29 Resources, 
11 Troublemakers, and 
24 Problems.

In terms of rarity, the main set contains

60 Common (C) cards, 
62 Uncommon (U) cards, 
60 Rare (R) cards, 
6 Fixed (F) cards, and 
16 Ultra Rare (UR) cards. 

There is a 1 in 11 chance for a Canterlot Nights booster pack to contain an Ultra Rare card in place of a Common card (an increase from Premiere's 1 in 13 chance).

Flutterbat is a "secret" Ultra Rare such that it is not listed in the set checklist, but it is still part of the set and still has the same chance to be obtained from booster packs as any other Ultra Rare in the set.

In addition to the main set, there is also a foil parallel set of 56 cards. Of these Foil (f) cards, 44 of them are foiled versions of cards found in the main set but are otherwise the same as their main set equivalent. There is a 1 in 4 chance for a Canterlot Nights booster pack to contain a parallel Foil card in place of a Common card.

The promo set of 19 cards cannot be found in booster packs. Of these 19 Promo (P) cards, 12 of them are foiled versions of cards in the main set, and 6 are unique to the set. Twilight Sparkle, Ursa Vanquisher has been previously released as part of the Premiere main set.
