Costs and Effects

A cost or an effect could be adding/removing twilight tokens, exerting a character, discarding a card, or any number of other possibilities. The costs for an action are usually listed before the word "to" (so the action takes the form of "pay X to do Y," with X being the cost and Y the effect). A card may not be played, nor an action taken, if its costs cannot be met. You may play a card or take an action that has no effect, as long as you can meet its cost.
