My friend and I just got Deluxe and are on our 4th game. So far in the first 3 games we have played UN Intervention like this. If my opponent played some event I did not want to go off I played UN Intervention to stop it. Kind of like a counterspell in Magic the Gathering. Upon reading the extended example of play on page 14 (US action round 3) the UN Intervention card is used in an entirely different way. In this case it is played together with your own card to cancel an opponents event. So my question is whether or not this card can be played like a counterspell in my first interpretation? Thanks.
It can't. It can only be played as per the extended example to cancel your own event.
