1000 Yu-Gi-Oh cards, most likely all from early to mid 2000s. yugioh TCG CCG lot

My sister graduated in 2006 and she played this for a few years before then, so I am guessing these are all early to mid 2000s. I cant read the stuff on the cards without a magnifying glass.

Roughly 1000 Yu-Gi-Oh cards. My sister said she sold all her First Edition and all her best cards back then so finding the expensive ones are probably very slim. Not sure what is in the box cuz I am not looking up individual cards when there are around 1000 (based on measuring the amount of cards to make one inch).

These were stored in a basement with moisture issues (but not getting physically wet), so many are a little warped from not being packed tightly 15+ years ago but most look unplayed.

She said she had a few boxes either in the attic or the basement or the cabinets in the garage, but this was what I found so far and I re-boxed them tighter into a box for them to ship.
