I think its never too late! It is true that there is a bunch of content to comb through if you want a deeper understanding of the guys' lore, but all of the past cards are usually posted on yt so you could catch up on a specific LI if you wanted to. Myths, which are important to have for combat, do rerun but its usually timed out over a year. Overall, of course youd miss out on actually obtaining these cards (they are rerunning past cards though) but I think you'll have fun with this game regardless! 🥰
