Hey there, thank you for the kind words!
- Queen of wands in Soloterrare missing is an error, you're correct to use the king rules and flip everything to queen. She will be added in the next update.
- Fukuzatsu as a whole is a modular game, if you wish to mix and match rules that is entirely up to you, just make sure that's clear to other players. Though cups in the base game is meant to be both a gamble to remove tarot and also a way to change your own deck. The less cards in your deck, the more likely you are to draw what you've currently got in play again. Embrace the chaos!
- This is correct that the player who is holding the line cannot put anymore men on deck, The other players must race to defeat the sea monster before the men are killed or the line snaps. This is where tarot come in useful to getting more sailors out or having an edge.
