When Cryptic Coat enters the battlefield, cloak the top card of your library, then attach Cryptic Coat to it.
(To cloak a card, put it onto the battlefield face down as a 2/2 creature with ward . Turn it face up any time for its mana cost if it's a creature card.)
Equipped creature gets +1/+0 and can't be blocked.
: Return Cryptic Coat to its owner's hand.
