Poster 'saleen123456' from MTGSalvation reports that the Mirrodin Besieged Buy-a-Box promo is named 'Mirran Crusader.' We don't know anything more than a name at this time, but a follow up post by user 'Crimson' contains an interesting point that might hint at what the card will be.
Fun fact: almost all crusader cards from the past were mono white, so I'm expecting a mono white here as well (or white artifact, who knows)
Most of them if not all has a protection from something
