Discard

Discard is a keyword action which takes cards from a player's hand and puts them in their graveyard. Discard is in the black part of the color pie. Discard spells are more often at sorcery speed, a few have been printed at instant speed. The target of a discard spell more often gets to choose which cards to discard. Cards which give the choice to the discard spell's caster cost more, as do cards which force a random discard. Random discard spells are said to be "unfun", so less of them have been made. The creature type Spectres are famous for causing players to discard cards when they are unblocked.
