When to research
Research before sending the Home City cards you want to improve: Maison du Roi adds its reward to future shipments, not cards already delivered. It is most valuable while several shipments remain; late in a match, fewer deliveries may arrive to repay the cost. Use the Trading Post or Tambo on a House of Bourbon palace for research. Research takes 30 seconds and costs 750 coin.
Shipment support and Trading Post access
Maison du Roi is an Industrial Age technology researched at a Trading Post or Tambo on a House of Bourbon palace. The 750-Coin research takes 30 seconds, adds one Royal Horseman to every future Home City shipment and enables Royal Horsemen to be trained at qualifying Trading Posts or Tambos. It therefore affects both future shipment value and local production at the correct alliance site. It does not add a Horseman to shipments already received.
Plan the deck and the forward site together
Research when the deck still contains useful future Home City shipments and a House of Bourbon site can be held. The added Horseman consumes population and arrives with later shipments, so leave space for it before sending those cards. For local training, protect the Trading Post or Tambo and compare the Horseman cost and queue time with a safer production building. If the match is nearly over or the deck has no planned shipments, the long-term bonus may not repay the Coin.
