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 2. 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.
1u: return cryptic coat to its owner's hand.
