I’m continuing with my final regular wotc binder, these are probably the least exciting ones to the public but there are a lot of ones i love deeply like legendary collection reverse holos side by side and many of the e-series trainers. Some trainer cards also give me so much nostalgy like the mysterious fossil that i remember opening a lot and having a full page of it as a kid, at some point i did put even all my multiples next to each others in my binder but it still was the only card in addition to fossil slowpoke that managed to fill the whole binder page 
i also do have some not that great memories from opening those base set boosters only to find out the rare was a trainer, but i guess i’m not the only one so it’s kinda a fun memory to share with others. Some excellent trainer promos too during wotc era.
I also have incredibly soft spot for beautiful energy cards so i could just stare and admire the original cosmos foil promo energys from different angles from time to time. Also those aquapolis special energys are so gorgeous that they gave me a push to go for the japanese p-promo equivalents
