Vorthax Aureum, Golden King

Flying, vigilance. Ward {2}
When Vorthax Aureum enters, you become the monarch.
Whenever one or more Dragons you control attack, reveal cards from the top of your library equal to the number of creatures that attacked this way. Put up to one Dragon card among them onto the battlefield and the rest on the bottom of your library. If you're the monarch, put any number of Dragon cards among them onto the battlefield instead.
