A Cube is a variation of gameplay for collectible card games. It is a player-made set of at least 360 cards created for the purposes of drafting, though as many as 720 can be used.^[1] Booster packs are simulated from the contents of the cube and are used to draft cards for play.^[2] Essentially, a cube is a self-contained CCG set that requires no additional cards to play. It has everything it needs to be self-sufficient and can be used repeatedly. A cube typically accommodates up to 8 players.^[3] In some aspects, a cube is constructed to be played like a non-collectible customizable card game or ECG (Expandable Card Game), also known as a Living Card Game (LCG).^[4] A cube's construction is done with a focus on what type of metagame is desired.^[5]

• Thematic – These cubes use certain card types to create a theme.^[6]
• Block or Set – These cubes replicate specific expansions so players can relive a drafting experience of an older set, and often contain multiple copies of common or uncommon cards.^[6][7]
• Custom – These cubes use cards from the entire history of a CCG. They're built using cards based on power level, notoriety, or personal preference.^[6]
• Singleton – A cube that specifically contains only a single copy of any card included in the set.^[1]
