I don't think they ever explicitly stated ranking reward will not reappear. That has just been common thinking until now because it never happened in 4 years ^^

I have noticed on some summons now that the put an exclaimer, that the card might be reissued but I'm very sure they have rereleased cards, that did not have that dislaimer. I don't mind it really but you just have to kep it in mind when using the MM.

And yes I agree, if you have problems fighting the LAW and a card you have could substantially make it better, by all means use it. And for art purposes there's no question either, everyone has to decide if it's worth to them ^^

I'm just saying you shouldn't use it only for the criteria of was it a ranking reward or was it an exclusive summon card. Try to focus on if the card will really make a big difference in your fights or not, no matter how exclusive or unique the card might seem because it might very well not be so exclusive anymore in the near future :D
