You can recruit from the Elite Deck after the first core tile appears.
From Page 4 of the Rulebook: (Prepare the round) "Deal new Crew Cards into the Crew offer equal to the number of actual players plus 2. If no Core Map tile has been revealed, deal Regular (silver back) Crew Members only. If at least one Core Map tile has been revealed, alternate dealing Elite (gold) and Regular Crew Members. (Elite, Regular, Elite, etc.)"
Thank you. I know the rule is in MK, but I just could not find it in ST Frontiers except for that one instance where it mentions that elite crew depend on scenario.
