Deck inspection attack
A deck inspection attack is an Attack card that reveals cards from an opponent's deck and does something with them. Trashing attacks and deck order attacks usually fall into this category. They often combine well with each other, in that some deck inspection attacks will let you determine what card is on the opponent's deck so you know how beneficial it will be to play another deck inspection attack; for example, Spy or Scrying Pool can let you set up an opponent's deck to have a good card to hit with Jester. In other cases, they conflict with each other, and playing a second deck inspection attack will cancel out the effects of a previous one; for example, Fortune Teller will leave a dead card on top of your opponent's deck, but attacking with Pirate Ship afterward will discard that card and will have only one chance of finding a Treasure card instead of the usual two.
Secret Chamber is a often a good defense against these Attacks, since it gives the victim some choice over what card the Attack will find on the deck.
Deck inspection attacks do not interact with the -1 Card token; the token is put back on the relevant player's deck once the card is done inspecting.

 Fringe cases
- Tribute and Chariot Race are not Attacks, but they reveal cards from an opponent's deck and have effects that depend on the revealed cards, so they fit into some of the same strategies as deck-inspection attacks (and Tribute is often mistaken for an Attack by new players).
- Sea Hag discards the top card of the opponents' decks, but the effect of the Attack does not depend on what the discarded card is.
- Similarly, Minion, Margrave, Soothsayer, and Legionary are Attacks that cause opponents to draw, at least, the top card of their decks.
- Bureaucrat, Ghost Ship, Haunted Woods, and Haunting do the opposite, causing opponents to put cards from their hand on top of their decks.
