To defeat an opponent that is self-healing, save as much AP as much as possible. Then, execute a series of special attacks at the correct moment.

If your only objective is to obtain ISO-8, you can get more of it by selling duplicate cards.

Participate in Tournaments frequently to unlock characters, earn rewards, improve your rank, and get higher ISO-8. The higher your rank, the more ISO-8 you can obtain by defeating opponents in less than three turns.
