Heya, this might be too late(5 months too late haha), but when making your suit decks, did you add the second major arcana card to the top?
Since Arrival's setup states(if I remember correctly) to add 2 cards from each suit deck, you should be adding 1 Major and 1 Minor card from each, guaranteeing at least 3 confidants in Arrival. Hope this helps :)
Hi! Thank you for replying! I don't exactly remember how I added the cards, but I think I (wrongly) picked at random from the piles so even though there were several major arcana cards (including ones on the top) per pile I ended up not drawing any by chance. At the end of Arrival, I retconned to give myself a circle and then picked correctly for the rest of the game.
