Just beat the Card Mode hack together with the PT-BR translation, and basically, everything in the translation worked fine with the hack. Good job, Dev Anj!
BTW, I managed to get all cards except for Uranus, which prevented me to use the Thunder Summon against harder bosses, thus making me have a hard time beating Dracula's final form. Hopefully, I had dozens of Spiced Meats dropped by all enemies that drop them instead of their cards, which I used lots of them to heal myself.
I know you don't want to spoil us about the card locations, but can you at least tell me on which castle location it's located? Hope it's not in the Arena lol
