I’m reading and I think this is true:
At the end of the turn, you collect the cards that are still on your Action Mat - which are cards you did not use as an event (instead used as an action or just not played at all as action or event).
Then you may keep up to two cards and discard the rest.
Then you draw until your hand is eight cards.
I no longer think this is true. I think that the cards remaining in the Action Mat at the end of Round Two are discarded.
