Notes & Combos
Honestly it's exactly what you think it is. I just took a page out of the TCG's book. I'm not sure what other people's reasoning behind going above 40 cards, but my logic is that yubel has a LOT of inoptimal starters/bricks. Going above 40 just lowers the chances you run into any one of them, but of course it's rarer to open a starter, However...
Adding the kash stuff literally boosts the deck's defenses and extension 10 fold. Kash unicorn is two FREE link mats. You'll easily get the 3 bodies needed to go into whatever line you want with fiendsmith since main deck Lacrima isn't around. Therefore, you can go into Beatrice + muckraker to get into the yubel line if you're stuck with the kash. (Also ripping out people's reqiuem with unicorn is so evil)
