If the Philosopher lands on a space that has a face up card from one of the 3 Draconic Lord decks, and he decides to use his discard ability on the card, when drawing a replacement card to encounter do you:
Draw an Adventure/Dungeon/Highlands card (depending on the region they currently are in)?
OR
Draw a Draconic Lord card that matches the same deck of the discarded one?
OR
Choose between the two options above at the players discretion?
