if the Joker is always 3rd card. I say there is joker every 3 cards.
Now if I want to use it with phrase after X cards.
Should I say:
A. There is always one joker after 3 cards.
B. There is always one joker after 2 cards.
So the joker arrives always after 2 or 3 cards if it is every 3 cards? Can you please explain? Thank you very much
