This is Really Good Game.

Please take care of Korean server, too.

Here Korea exists many big whales but using old version now.

If you spends enough time until lv 90, you can buy promotion stone with diamond at shop.(It's better not to buy promotion stones until you can buy 70 promotion stones for 50 diamonds. Also I recommend you to spend a box of gold coins per hour item after you reach lv80)

I'll show you some recommended deck ideas, so please refer to them and raise heroes well.
