During the Deployment Step, the player has two options.
On a Mission or Facilities card that is currently in play, the player may play a Character card from their hand according to the rules of the cards. The alternating player then has an opportunity to dispatch a card and control alternates between the two until one player clears the cards conditions. Any cards played must also make sure not to violate either the Link rules or the Unique Rule.
If the Mission or Facilities card is a new one, the player must play a Leader card. If they cannot, control passes to the other player. If they also cannot, the card is left unresolved until the following turn. Because of this, it is important for players to ensure they have a Leader card on hand before playing Mission or Facilities cards.
The player does nothing and skips their turn. The other player gets a chance to deploy. If they cannot, the card remains unresolved.
