<P> The following table lists the card releases by their type or expansion name, their North American date of release (with the release in other regions typically within a day afterward), the date of the expansion's transfer to the Wild format, and the distribution of cards within that release . Blizzard has announced there will be three expansions of about 130 cards each in 2017 . </P> <P> Blizzard has adopted a "Year" moniker to identify when expansions have been retired from Standard format; the first, "Year of the Kraken", lasting from April 2016 to March 2017, retired the Curse of Naxxramas and Goblins vs. Gnomes expansions, while the "Year of the Mammoth", starting in April 2017, retired the Blackrock Mountain, The Grand Tournament and League of Explorers sets . Initially, retired expansions were not available to purchase, but in July 2017, players were able to purchase these and all future expansions that are retired from Standard on Blizzard's website . In the "Year of the Mammoth", Standard moved some Classic cards to the "Hall of Fame" set that is not playable in Standard but still can be obtained and available to play in Wild format . </P> <Table> Collectible cards breakdown <Tr> <Th> Set (abbreviation) </Th> <Th> Release type </Th> <Th> Release date </Th> <Th> Removal date from Standard format </Th> <Th> Total </Th> <Th> Common </Th> <Th> Rare </Th> <Th> Epic </Th> <Th> Legendary </Th> </Tr> <Tr> <Th> Basic </Th> <Td> Core </Td> <Td> March 11, 2014 </Td> <Td> N / A </Td> <Td> 133 </Td> <Td_colspan="4"> N / A </Td> </Tr> <Tr> <Th> Classic </Th> <Td> Core </Td> <Td> March 11, 2014 </Td> <Td> N / A </Td> <Td> 239 </Td> <Td> 91 </Td> <Td> 80 </Td> <Td> 37 </Td> <Td> 31 </Td> </Tr> <Tr> <Th> Reward </Th> <Td> Core </Td> <Td> March 11, 2014 </Td> <Td> April 26, 2016 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> </Tr> <Tr> <Th> Curse of Naxxramas (Naxx) </Th> <Td> Adventure </Td> <Td> July 22, 2014 </Td> <Td> April 26, 2016 </Td> <Td> 30 </Td> <Td> 18 </Td> <Td> </Td> <Td> </Td> <Td> 6 </Td> </Tr> <Tr> <Th> Goblins vs. Gnomes (GvG) </Th> <Td> Expansion </Td> <Td> December 8, 2014 </Td> <Td> April 26, 2016 </Td> <Td> 123 </Td> <Td> 40 </Td> <Td> 37 </Td> <Td> 26 </Td> <Td> 20 </Td> </Tr> <Tr> <Th> Blackrock Mountain (BRM) </Th> <Td> Adventure </Td> <Td> April 2, 2015 </Td> <Td> April 6, 2017 </Td> <Td> 31 </Td> <Td> 15 </Td> <Td> 11 </Td> <Td> 0 </Td> <Td> 5 </Td> </Tr> <Tr> <Th> The Grand Tournament (TGT) </Th> <Td> Expansion </Td> <Td> August 24, 2015 </Td> <Td> April 6, 2017 </Td> <Td> 132 </Td> <Td> 49 </Td> <Td> 36 </Td> <Td> 27 </Td> <Td> 20 </Td> </Tr> <Tr> <Th> League of Explorers (LoE) </Th> <Td> Adventure </Td> <Td> November 12, 2015 </Td> <Td> April 6, 2017 </Td> <Td> 45 </Td> <Td> 25 </Td> <Td> 13 </Td> <Td> </Td> <Td> 5 </Td> </Tr> <Tr> <Th> Whispers of the Old Gods (WOG) </Th> <Td> Expansion </Td> <Td> April 26, 2016 </Td> <Td> TBA 2018 </Td> <Td> 134 </Td> <Td> 50 </Td> <Td> 36 </Td> <Td> 27 </Td> <Td> 21 </Td> </Tr> <Tr> <Th> One Night in Karazhan (Kara) </Th> <Td> Adventure </Td> <Td> August 11, 2016 </Td> <Td> TBA 2018 </Td> <Td> 45 </Td> <Td> 27 </Td> <Td> 12 </Td> <Td> </Td> <Td> 5 </Td> </Tr> <Tr> <Th> Mean Streets of Gadgetzan (MSG) </Th> <Td> Expansion </Td> <Td> December 1, 2016 </Td> <Td> TBA 2018 </Td> <Td> 132 </Td> <Td> 49 </Td> <Td> 36 </Td> <Td> 27 </Td> <Td> 20 </Td> </Tr> <Tr> <Th> Hall of Fame (HoF) </Th> <Td> Core </Td> <Td> April 6, 2017 </Td> <Td> April 6, 2017 </Td> <Td> 10 </Td> <Td> </Td> <Td> </Td> <Td> </Td> <Td> 5 </Td> </Tr> <Tr> <Th> Journey to Un'Goro (Un'goro) </Th> <Td> Expansion </Td> <Td> April 6, 2017 </Td> <Td> TBA 2019 </Td> <Td> 135 </Td> <Td> 49 </Td> <Td> 36 </Td> <Td> 27 </Td> <Td> 23 </Td> </Tr> <Tr> <Th> Knights of the Frozen Throne (KFT) </Th> <Td> Expansion </Td> <Td> August 10, 2017 </Td> <Td> TBA 2019 </Td> <Td> 135 </Td> <Td> 49 </Td> <Td> 36 </Td> <Td> 27 </Td> <Td> 23 </Td> </Tr> <Tr> <Th> Kobolds and Catacombs (K&C) </Th> <Td> Expansion </Td> <Td> December 2017 </Td> <Td> TBA 2019 </Td> <Td> 135 </Td> <Td> TBA </Td> <Td> TBA </Td> <Td> TBA </Td> <Td> TBA </Td> </Tr> <Tr> <Th_colspan="4"> All released cards (through KFT) </Th> <Td> 1324 </Td> <Td> 465 </Td> <Td> 338 </Td> <Td> 204 </Td> <Td> 184 </Td> </Tr> </Table> <Tr> <Th> Set (abbreviation) </Th> <Th> Release type </Th> <Th> Release date </Th> <Th> Removal date from Standard format </Th> <Th> Total </Th> <Th> Common </Th> <Th> Rare </Th> <Th> Epic </Th> <Th> Legendary </Th> </Tr>
