Targets
The bank is 150 cards (DESIGN.md 7.2.1): 52 exterior with Shields and Armor, 52 interior with the captain, 10 gear, 10 mods, 6 food, and 20 economy and utility cards. The bar at the top counts your picks against these; change the targets under Balance.
Roles
Of the 104 exterior and interior cards, aim for about 40% filler, 20% support, 15% scalers and quest cards (at least four quests), 10% centerpieces, 10% economy riders, and 5% tag payoffs.
Sectors
Each prototype sector needs a lean that shows in its pools: Mining armor and boarding defense, Trade Hub shields and money, Frontier weapons and boarding, Research systems and mods. Keep at least 15 cards per source sector so no merchant pool runs thin.
Watch for
One Shields card and one Armor card fit per exterior row, so pick models with clearly different jobs. Cards that grant extra activations are the costliest to build; their notes say so. Nothing creates cards during a fight. Items take a full cargo slot until attached.
