To share my understanding (but would welcome someone either backing up or discussing ).
1 - Can you reveal more cards than are still in your deck by reshuffling? Or are you out of luck?
If I understand your question, I believe there are two scenarios:
- You play a card like Guiding Spirit (Discard and redraw that many cards) in which case you discard your hand, draw from your deck back up to the same number - reshuffling the discard if necessary to hit the required number.
- You are hit by an obstacle, or play a card (e.g. deathtouch) which specifically uses the phase "from the top of your deck", in which case you are limited to how many cards are left in your draw pile.
Unrelated question: We played Extraction 3 player. The Extraction card says to use all the normal rules of Crossfire.
We were unsure if it was referring to the mission, "Crossfire" or the rules of the game itself...Crossfire.
This mattered because the Crossfire mission says if you play with 3 players to not draw a Crossfire card (too many Crossfire words!) round 1.
2 - So...if you play Extraction 3 player do you draw a Crossfire card round 1?
Its actually secret option number three - that phase is used under the header 'Obstacles and Crossfire' so refers to using the normal rules of the crossfire deck - i.e. draw a new crossfire card at the start of the first runner's turn.
There are no rules for fewer players in Extraction - you always draw a crossfire card!
3 - When playing Crazy Katie's Towing mission can Wreck cards chain into more Wreck cards? The wording was a bit odd. IE Do Obstacles flipped from Wrecks come from the Highway deck or the normal deck?
I play as though all cards which are drawn from flipping at the start of the round, including those extra from wrecks, come from the highway deck - the only cards which are drawn from the 'standard' decks are those caused by other events, such as crossfire cards.
This does mean you can end up with a lost of obstacles at the start of a round yes
Hope that helps, and I am happy to be corrected!
