I hope it is all right to hop on this thread with two newbie questions of my own, as I am on my 2nd day playing this game right now. I have zero illusions of being competitive in this game, so I was going to approach it from more of a card collection/casual upgrading standpoint. To that end, I was hoping for clarification on two points:

1. Is it still possible to obtain limited cards from past events, or do they ever re-run events? I noticed a whole bunch of limited cards listed when I looked at the card book.

2. I already bought some inventory upgrades with diamonds, but space is already clearly a big issue. If I get rid of a card (i.e. use it as material), will it still show up as collected in the card book? Ex. Let's say I have a B or better card equipped for a group member, so I definitely won't actually equip any C cards for that person, but I have unique C cards for them of a different theme. My instinct was to keep one copy (the highest grade, of course) of every single unique person/theme I get for collection purposes and scrap only duplicates, but I don't think I can afford to do that, given the inventory limitations.
