In your discard phase you receive, by default, one discard phase action. You may use a discard phase action to put an event card in play (no more than one per phase) or to discard a card from your hand (and draw to replace it as usual). Some effects may change the number of discard phase actions you receive or may give you alternate ways to use your discard phase actions. Discard phase actions not used in this phase are lost; they cannot be saved for later.
