This one is a bit tricky and depending on luck but you can also boost this one in a private match. You have to complete a set for yourself and your enemy by using the "Forced Deal" card. Try to save them up until everything is set (there are three "Forced Deal" cards in the stack). try not to complete any sets before doing this. Remember that by pressing LT/RT you can take a closer look at the cards and sets of your enemies.
