var/list/tempHouseCards = typesof("/obj/House_Cards/[player.House]")
Problem description:
I want all the children of /obj/House_Cards/[player.House] in the list, but not /obj/House_Cards/[player.House] itself. What's the best way of achieving this? I'm hesitant to loop through the list and check istype() on all entries.
typesof returns a list, so literally just subtract that item from the list
