Good answer!
I think the "arrange the other 4 in any way you want" should be "put the other 4 in any order, all face up and with the same orientation, that you want."
There is a clever card trick -- again using two people to impress a third -- where ten cards, at least one of them a ten of any suit, are laid out on a table with the same arrangement as the suit markers on a ten card. Then the mark third person picks any of the ten cards, or even multiple cards, pointing them out to one of the two cons mentalists out of sight of the other. Then the con mentalist who knows the card(s) chosen makes a bunch of apparently random touches of the cards on the table, and the other con mentalist guesses the chosen card(s).
And the trick is that the ten card on the table is used as a map of the other cards, so it will be touched on the suit marker corresponding to the chosen card.
