>>52880426>Is double sleeving for binder a bad thing?No, it's not. I have done this and all cards came out just fine... Though it's quite unnecessary to do so when you have side-loading pages, which you have, great!
>ETB sleevesI personally wouldn't advice you ETB sleeves, I've heard they aren't the best. If you want decent outer sleeves, get yourself Ultra PRO penny sleeves or (big enough) Dragon Shield sleeves.
>I also can't decide should i put only less valuable cards in this binder or literally ALL of them. This why i put only cheaper ones. I have vintage gengars and modern ones like that full art with Mistortune Sisters in multiple languages but i keep them in top loaders.It's not necessary to put the more valuable cards in toploaders, I put more pricey cards in my binder too. They are fine in there. If you're worried about your more valuable cards, then put them in a toploader, if that makes you sleep well at night.
>Should i just say "aww fuck it" and do a literal gengar chad binder with all cards?Why not? If you have the money for it and still enough pages left, I'd say go for it! I'd love to see your wonderful Gengar binder in the future!
