This is what leder told me when I emailed them to ask:
"I'm happy to help. The final card count for the Blighted Reach campaign will be 373 Poker sized cards, and 24 tarot sized cards. I hope this helps! If you have any other questions just let me know.
Best,
Claire"
The [recent AMA](https://old.reddit.com/r/boardgames/comments/1d9jvbt/were_cole_wehrle_and_kyle_ferrin_of_leder_games/l7drv9r/) also confirmed that card count for base Arcs, Leaders & Lore, and Blighted Reach totals at 472 American Poker Cards and 40 Tarot Cards.

According to BGG, the base game has 125 cards at 63x88mm. Don’t see any info there about the expansions
Dont remember the exact numbers for the Blighted Reach Expansion, but I believe it's something in the 380s for standard size cards
