It is seen in anime that Hisoka hurls many cards, yet he never runs out of cards. He was never shown to buy, borrow or steal a deck of cards either. Moreover, he gets his cards out of nowhere in his hands (he never slips his hands into his pockets or his clothing to fetch cards).
So does he have the power of conjuring cards?
Similarly, does Illumi have the power of conjuring needles, and does Gotoh have the power of conjuring coins?
Or do they (i.e. Hisoka, Illumi and Gotoh) belong to the category of Emmiter?
