Most of these games however typically use a specially made deck of cards designed specifically for the game (or variations of it). The decks are thus usually proprietary, but may be created by the game's players. Uno, Phase 10, Set, and 1000 Blank White Cards are popular dedicated-deck card games; 1000 Blank White Cards is unique in that the cards for the game are designed by the players of the game while playing it; there is no commercially available deck advertised as such.
