Does anyone know why the cards were produced like this or have any info on the matter?
Not sure, other than Wizkids possibly wanting to preserve a South China Seas theme to those specific cards due to how most or all of them are former Jade Rebellion ships that were captured/etc.
I imagine that there are similar cards among the other factions like these?
It’s the case for all the OE SE cards that came in the large tins, numbers 147-170.
