I just bought my first Data Pack a few weeks ago (not that I ever get to play but I'm a fluff nut) and I bought 23 Seconds I like the cards but I ran into a bit of an issue... They have this secret thing... What sets come with secret so I can use these Ice Breakers?

You mean "stealth"?

There are a number of cards with the subtype "stealth" in the game.
