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.

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).
