(and no, no the bs low quality series where they summon Tagabatha or other "historical figures BS" or going "I SUMMON OP STUFF X" but like : i have a fire mage (GIRL cough), i also use this blue dragon (GIRL cough), and also use this assassin (GIRL COUGH))

Or mentioned elsewhere the joke about "MC use card to become invincible but cant deal dmg and feel pain x2 + card boost everyone PAIN FACTORx2 + card feedback the pain x5 to enemy" something like that. It was the first "trolling strategy" of MC.
A bs mega effective working one, funny to the point to get cramp stomach by laugher. And why i claim that CNs can rival Konosuba. Bc they truly write Light Novels like jp as good as To-Aru-majutsu complexity.
One got a darkish cover, a girl in middle of what seems the road/city and shadowy figures around. (gosh the cover is my most fav, but never understood what it is XDDDDD)
