Searching Deck/Showing your oppt the card.
Lets say a card tells you to: search your deck for X, show it to your oppt and put it into your hand.
When you show your oppt. the card(s) do they have the right to read the card(s) before you put them into your hand or do they only have the right to verify that, that(those) card(s) meet the critira for X and then you put them into your hand without them having a chance to read the full text of the card.
I am well aware that cards in play are allowed to be read by either oppt.
