HBG Specialize mechanic
i Would try to make it via Clone States that this sets new copyable values
i just need to check that it doesn't mess with ColorIdentity
Specialize + Brawl Commander:

What is the color identity of a card with Specialize? In limited, these cards can be specialized into any of the five faces, based on the color/land types of the cards you draft. In Brawl, when used as a commander, you have to chose which specialize face you're using and that becomes its color identity. However, when building a Brawl deck with a three-, four- or five- color non-Specialize card as your commander, you can include a specialize card and be able to specialize it to any of the colors you have available, without the need to choose a specific face to play it as in deck construction. In a traditional appraisal of color identity (i.e. "what mana symbols are in the cost and rules text of the card?") these cards all have a color identity of {W}{U}{B}{R}{G}.
