Help with Strategy (Card Management)

Did you know that the replay feature was recently added? You can see it by pressing "Detailed History" in the rankings and then "Replay Playback" at the bottom right. Furthermore, there's also a recommended replay feature. Press "Growth Info" at the bottom left of the main match, and you can find it under "Recommended Replays" at the top right. You can see clear formations and card management for your own Plv. You can also enjoy it by thinking, "How is it possible to clear this with such a low Plv!? What kind of formation did they use?" It's a wonderful feature that's also educational for those who teach others.
