Five Card Deck

Return up to five cards from your hand to the
top of your library in any order, then shuffle
your library. Reveal cards from the top of your library equal to the number of cards returned to your library this way. For each revealed card,
Five Card Deck deals 1 damage to you if the revealed card shares a card type with any of the other revealed cards. Place all revealed cards into your hand.
