Sleeve questions

Hey all new to riftbound I'm a refugee from Yu-Gi-Oh! I have tons of novelty border sleeves from my time playing Yu-Gi-Oh specifically from imperium duelist. I know using separate sleeves for Mana and your legend is okay.

Usually with these sleeves you sleeve the card underneath before hand and that works fine because Yu-Gi-Oh cards are much smaller. These border sleeves will fit as is with riftbound cards since the border sleeves are standard size. I was wondering if anyone has experience using this type of combo bc I really want them to fit because the sleeves are really nice 😭.

Alternatively it could be an angle to put a clear over sleeve on them. If that is something y'all have don which sleeves do y'all recommend.

This is absolutely first world problems I'm just curious and wanna know if anyone has insight!
