Few things to note for the upcoming card game in JP:
1. At the start of battle you have 1 chance to redraw all 4 cards.
2. You cannot hold more than 10 cards on hand. No limit for your deck.
3. There are 4 slots for strikers and 2 for specials. Strikers can be in front row or back row, and can move between them by spending cost. You can only activate EX skills of front row strikers and specials.
4. Important: strikers' HP carry over to the next battle. They don't heal automatically. There are Resting Stage where one of the options is to heal your strikers, and another option is to bring back strikers whose HP reached 0.
5. There is an upgrade tree that you can access outside of a run.
