If you're willing to do the extra work, as in checking back and forth for unknown cards and finding them on this extensive list

That is the whole catalog of cards known for JP and EN. Maybe I didn't search on google hard enough but I bookmarked this to see reveals of cards that I couldn't or will never get. It may be time consuming and tedious to check back and forth but they were generous enough to put all of each individual cards art there. For example you can see Runa Kamiwano's lvl 100.

That is great thanks, it's not too much trouble to look through and now i know which cards i will level up
