Saga

From Publisher's website:
SAGA is a easy-to-play cardgame based on a fantasy world, full of fairies, knights and dragons. This is a standalone cardgame (not a CCG) so all you need is this box.

Winner is the player with biggest points when the game ends.
Points of cards in fields and hands switch the way of scoring, depending on how the game ends.

You have to watch the game carefully. The player with the best strategy and a sharp eye will win in this ever-changing game.
