Curve out

To "curve out" is to play a card on each turn, in accordance with a planned mana curve. To play a spell with a converted mana cost of one on turn one, a spell with a converted mana cost of two on turn two, a spell with a converted mana cost of three on turn three, and so on, is curving out. It is considered the most optimal way for a deck to work, especially creature based decks, such as aggro decks or Limited decks and is effectively the opposite of mana screw and mana flood, e.g.: "I got mana screwed on two lands, and he just curved out for the win".
