Someone in the comments section of the game mentions that they mix and match starter cards. Essentially doing a little deck building. I didn't think of that at all. Is this also possible?
Yes. According the to CW rulebook you may construct your starter deck after finishing the draft. The rules for constructing your starter deck is that you must use 12 cards and you must still have 2 of each color (so 2 NF blue, 2 CW blue or 1 of each). Should players wish to use all NF starters or all CW starters that is perfectly fine.
