@@skrrt8405 I want you to try it in the duo mode. You'll see how Echo and Cards are used by your teammates and opponents. As for cards and echoes, it is recommended that you read the descriptions carefully. When entering the field at the beginning of the game, try to be calm. Mana management and card movement are important. You can try it out in practice mode if you're worried about your score dropping. And because the coins in the game are limited and high-ranking players have a lot of levels cards , you should upgrade the cards which you use regularly. Blue potion can be used if you feel allergic to protect your points. Finally, I would like to encourage you to try playing 4-5 times a day as because I was also afraid and tired of competing.
