"WebThe "mana curve" is the application of mana optimization theory to deck construction. By organizing the cards that are to go into a deck by their casting cost, a player can see how likely they will be able to optimally utilize each turn's mana (i.e., to play a card or cards with a casting cost or costs with a total equal to the mana available on that turn). In order for a … " - How is a standard curve constructed
