The Collector characters are characters that are not available anymore at the shop, except in the Crypto Pack. You can only get them from other players on the Market, by winning them in ELO Mode, or from the premium track from the wheel.
There are currently 141 Collector cards.
You can spot a Collector by their name, it ends in "Cr".
Which characters become Collector is decided by the Staff, and you'll be alerted by a home page news one week in advance. At that moment, all existing sales on the Market of the future collectors are cancelled and new sales are blocked for 24 hours (to spread the news). The soon-to-be Collector remain in The Shop's boosters for a week before becoming Collectors.
Any card which is not an LD card can become a Cr card, does not matter the rank of a card or the market price etc.
They are the third hardest type of card to get in the game, following Mythic and Legendary cards (See Common, Uncommon, Rare, Legendary and Rarity).
