Card: I Summon the Stars to Come Out and Fight

[Single heroine + city + system + cards + not brainless + funny] Mu Chenyu's soul travels to a parallel world where battles are embodied by cards. Here you can fight in a turn-based manner, or you can summon them to fight together. However, this parallel world was invaded by alien beasts and fought to the death in exchange for a stable living environment, but it would not last long. The space would be torn apart at any time. At that time, there would be a large number of alien beasts invading, and this world would face great danger. Mu Chenyu summoned the characters in the Star Railway through the system to fight. I heard that your shield master's shield is very thick. I wonder if you can blow up my Jeppard's shield? I heard that your crossbowman has high single-target damage? Then my Xier will perform a nuclear explosion for you! I heard that your elf queen has a lot of milk supply. I wonder if my Rakshasa can sustain the milk supply. Can you handle it? I heard that your shadow man can slow down the appearance. Let's get to know my Bronya to increase the damage. Who said you can't pair cards with three auxiliaries and one C? I'm going for a nuclear explosion, do you understand?
