Rulings

2014-11-24: Each of the last two abilities is linked to the first ability. They each refer only to the choice made as a result of the first ability. If a permanent enters the battlefield as a copy of one of the Sieges, its controller will make a new choice for that Siege. Which ability the copy has won’t depend on the choice made for the original permanent.
2014-11-24: The words “Khans” and “Dragons” are anchor words, connecting your choice to the appropriate ability. Anchor words are a new rules concept. “[Anchor word] — [Ability]” means “As long as you chose [anchor word] as this permanent entered the battlefield, this permanent has [ability].” Notably, the anchor word “Dragons” has no connection to the creature type Dragon.
2014-11-24: Each Siege will have one of the two listed abilities, depending on your choice as it enters the battlefield.
