Brisela does not count as a commander after melding

From Discord user Ritsuki Tomori:

> Brisella the voice of nightmares doesnt properly register as a commander for the purpose of commander damage and other mechanics if you meld while bruna the fading light is your commander as it should

Judge ruling cites that whichever card was the original commander retains this marking after melding. [See Gatherer](http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=414305)
