Orvar and cloaked cards

Hi, I have a [[Vannifar, Evolved Enigma]] commander deck centered around blink and I was thinking of the possibility to add an [[Orvar, the All-Form]]. It's mostly to copy already face up cards that I wish to blink again, but I can't find any ruling related to copying a cloaked card. Is the created copy just a 2/2 with ward 2 or would the copy be able to transform if I pay the mana cost if it's a copy of a face down creature card?
