Sneaky-Sneak after combat?

[MunchkinMan]

It's important to remember that just about any card that is not an Item, Race, Class (or similar thingie), persistent curse, or Treasure that doesn't give a persistent bonus is going to follow the play-resolve-discard dynamic, which means that it doesn't have to say "usable once only" like an Item would need in order to be discarded once its effect is over. There may be some exceptions to this, but they should be recognizable given the text on the card itself.
