It’s important that your spectator randomly move around in no particular order and even repeat cards. This way, the spectators won’t think that you’ve prearranged a certain order. For example, the third card that the assistant touches is the chosen card.
Also, make sure that your assistant is consistent in how he says “is this the card?” and doesn’t make any odd movements or stances. Make this one look random and you should have some fun with this one.
