Yours is an absolute utopian speculation. I will be truly surprised and eternally happy if arkanauts alone will see six(!) card variations. I just don’t believe it will happen. If I was to bet I’d say each get a generic representation like the UW warband with some extras. So a thunderer, an arkanaut, a bubble boy with spear, couple leaders and we’re done. On the other hand as I write this I wonder how much extra is fair to assume. LoN had a ton of cards while aquamen - not so much.
2 arkanaut
2 bubbleboiz
1-2 thunderers
2 leaders
This is 8 cards which on one hand is more than some but less than others. I hope to be ridiculously wrong and excited when Warcry devs surprise me yet again with 25 fighter options
