After playing a few games with new players yesterday I've noticed that there seems to be a common mistake made during the Setup Phase of the game. In the two games I was the Red Player my opponents, both offered me their decks of Objective, Deployment, and Condition cards and asked me to remove one. I refused to do so and then they themselves removed a card from the "hand" and then laid the other three out. This is incorrect.
Step 5 of Setup on page 6 of the RRG states:
QuoteReveal Battle Cards: Shuffle the objective, deployment, and condition decks separately. Then, draw and reveal three cards from each deck, laying out each category in a horizontal row oriented right side up according to the blue player’s side of the battlefield.
Notice that is says to shuffle the decks and then draw and reveal three cards from each deck.
Furthermore, Step 3 of Game Setup on pg. 7 of the Tournament Regulations states:
QuotePlayers shuffle the blue player’s objective, deployment, and condition decks separately, then draw and reveal three cards from each deck, laying out each category in a horizontal row oriented right side up according to the blue player’s side of the battlefield.
The first thing to notice here is the word Players at the beginning of the rule, notice the plural form of the word. The second thing to notice is that this also says to shuffle the decks and then draw and reveal three cards from each deck.
This is a arguably minor distinction but an important one as it eliminates the possibility of the Blue Player fixing their decks in such a way that they can determine which Objectives, Deployments, and Conditions show up in which positions of the Battle Card array.
