"Work as if you live in the early days of a better nation"
I suppose, but correct me if I'm mistaken, that a player can activate a capability whose condition are met whenever it pleases them,that the player do not need to use an action for activation. Furthermore, may a capability be activated out of turn?
"As soon as the conditions of activation are met, players may activate the Capability card. Once a Capability card is activated, it cannot be deactivated unless the card says otherwise."
If they can fulfill a condition out-of-turn then the card will activate at that moment.
