Searcher

A searcher is any card allows you to see the entire Main Deck to look for a card(s) from it.

When an effect requires you to search for a card of a specific type in your Deck, then you must reveal the card to your opponent; and if you have none left in your Deck, then you must reveal your Deck to your opponent.

After every “search”, the Deck must be shuffled (in case of searching for a card to place on the top or the bottom of the Deck, the Deck is shuffled before placing the card).
