In the Strategy guide it says
and in the Deck building guide there the example is based on the same proportions of cards.The typical MotG Playbook deck has 28 cards, broken down as follows: 4 Audibles (14%), 10 Touchdowns (36%) and 14 Field Goals (50%).
However, in the Deck Building section of "Instructions for play", it says:
.The deck must have at least 12 “Touchdown” cards.
So, I guess only one of these is the correct one, but which?
