On your turn, you must perform two Main Actions.
There are two possible Main Actions: Play a card and Activate a card.
You may perform two different Main Actions or the same Main Action twice.
Starter cards are activated for free.
To activate a Villager card, however, you must remove 1 Supply from it, returning the token to the Reserve. If a Villager card does not have any Supplies on it, it cannot be activated in this way.
Even though you may Activate a card twice on your turn, you cannot choose the same card twice with this action.
In addition to your Main Actions, you may also take any number of Free Actions, before, in between, or after your Main Actions.
