I Have a Super Awesome Card Making House

This is a story that began in a refugee camp in a small border town. "Brother Heng, we are trapped, what should we do?" "Don't worry, I'll make an invisibility card first." "Brother Heng, they are too arrogant, we can't defeat them." "Don't be afraid, wait for me to repair this legendary battle card first." "Brother Heng, we are surrounded by a large army, and our brothers don't have enough weapons." "Wait for me one night, and I will arm my brothers to the teeth tomorrow." "Brother Heng, why are you so good at making cards?" "Hey..." I have a super awesome card-making room!
