unsecured credit cards for student

i'm student and i already have slice but wanted one more one more unsecured credit cards for me
say i get 5k per month so which would be great for me
my cibil score is 729 so i think i can get it at most places
i'm new to credit cards and don't know much about them
my expense are not going to much exceeded 5k (just was in need to some money)
and in upi i spend near about 200 per day

i'm not sure about benefit provided by credit card just wanted cause i need some money and i'm sure i can pay it before the deadline

P.s i already have slice but was just curious that what would be best option for me
