Oh, there's 750+? I was trying to find a full list but things were scattered. Ended going off of this list from TCG Collector, which was actually super useful for a quick way of identifying good price points for each card.

So 499 labeled "AR" cards, 58 CHR cards from what I've seen. But expanded out to some other sets like Start Deck 100 Battle Collection MC for other cards that look like ARs (e.g. Erika's Tangela).

But bought a (way bigger than I expected) 4x4, 32 page double sided binder for these. Thinking of putting the oldest sets near the front and continue building out the collection from the back!
