I'm sad that this didn't get a proper resolution, but to be honest it was just a worst version of a typical Yu-Gi-Oh arc. Granted yes it has the isekai angle, but Yu-Gi-Oh also has constant explorations into cyberspace (Duel Monsters) the spirit world (GX) the astral world (Zexal). There was nothing that really set this apart other than it was blatantly MTG as opposed to derived from MTG (like Yu-Gi-Oh's duel monsters original was). It never really had a chance from the start, but I'll say some of the designs are interesting. I hope the author gets another chance to do better.
