I've got 4 sets of the Core Set (in order to build all of the deck combinations) and realized that there doesn't appear to be a clarification on the number of cards that go into the Encounter Deck. I know I match symbols, but how many of each individual card go into the Encounter Deck? Player Decks are 50/3. Does Encounter Decks follow the same rule? Do I ignore all of the extra encounter cards I have, and just play as though I only have a single set of encounter cards, but more of the others?
Secondly, has anyone tried to 'tweak' the encounter decks by adjusting the quantities? For example, in the Passage Through Murkwood scenario, I've played with the list to be heavy goblins (3/card max), as well as a deck with stronger spider themes.
