Do you find Arcana Forced ATK and Strong DEF in the Rare Medal shop? That's it. You need to buy more of these two Arcana and upgrade the card you want to max with the Arcana and the upgrading material. If the level of the card is maxed you can upgrade the card's stats with the arcana and a N card. Repeat these steps until you get max ATK/DEF (19999 for ~SR, 29999 for UR)
