I think some Playtest cards were designed for Un-sets, some just for Fun, and some for Regular sets. They were not printed at the time they were tested, but now they are printed Sad they didn't include Mox Crystal.
For our group, we will put in cube 3 cards, which I think are cards OK for regular sets:
Frontier Explorer
Innocuocus Insect
Unicycle
We test 3 other cards (they are really powerfull and more Un-cards):
Growth Charm
Truth or Dare
Command the Chaff
I think rest of the cards are just fun/bad un cards or cards with not clear direction how to use them (for example Gold Mine - which players want to bend other ways than wotc intention) + Puresteel Angel (great, but very unfun)
