She also wrote the Crystal Tower raids, the Far Eastern "half" of Stormblood, and Endwalker (which despite the strident criticism on this forum was well received in the wider community).
Have yet to encounter work of Ishikawa's I don't enjoy.
I played Master Duel for a few months but then they changed it so you only got matched with people of the same ranking (before it was bracket based, so Gold could play any other Gold player etc.) and being able to play fun decks wasn't viable for even daily progress. Built a meta deck and clawed my way to Diamond, then noped out because it remined me metagaming is a necessity in TCG / CCGs and I just want to play my big dumb Red Supernova Dragon (poor boy doesn't get an animation). Plus the pull rates are ass.
I understand how to play it, but the level of metagaming necessary to scrape out wins past Gold V is egregious. Plus Master Duel is JP format only (or was when I played it), which allows obnoxiously oppressive cards like V.F.D., Rhongo, Imperial Order, etc. Yeah, just get Legacy of the Duelist if you're just looking to play... only problem is it's a few years out of date (Master Duel isn't quite current, but it gets regular updates that keep it closer).
