So, by "LUX oriented cards" how do you determine that? I'm looking at the Queen Minnie Assist Card from the last Valentine event and it's stats are HP+18935/LUX+182 HP'd. Is that good enough to max out?
To find out if a card is Lux-oriented, you have to compare it to other, recent cards.
The wiki helps with that. The wiki tries to identify which cards are HP or Lux oriented using the stars on the left side of the table (which Google translate to "Hiroshi" and "Evening," for some reason), but they're sort of inconsistent and it's better to look at the numbers. Treat the Key Art and Key Scene cards separately, because their stats are higher by default.
By looking at the wiki, I see the best Lux-oriented assist cards are ~180% in terms of Lux gain, with HP hovering just short of 19 000 on average. The best HP-oriented cards have HP around 24 000, but only have Lux boosts of 155% or so.
With careful use of the Ultimate Card System, you can actually maximize any SR+ card, but if you want a head start, the Minnie has pretty good, lux-oriented stats that will start you off with a sprint.
