i thought about something the MC can make card's like lego since it drains his stamina can't he make small parts and use his card combined and make all the small parts into the full thing. He can also make a card holder that it's function is it will always give the MC the card he needs at that time like if he is about to save someone and is being attacked his card holder will shoot out a specific card to help him out.
