How to Do This Trick?

Hey everyone, I'm intermediate in card magic and know quite a few moves in the craft, but I just watched a trick RickyEdit showed in one of his videos, and I can't figure out how it's done. If someone could explain the technique used for this trick, I'd really appreciate it😁.
