Official rulings
Five official rulings apply to Frontier Siege, newest first.
- 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.
- Each Siege will have one of the two listed abilities, depending on your choice as it enters the battlefield.
- The "Khans" ability triggers at the beginning of both your precombat main phase and your postcombat main phase. Unused mana is lost at the end of each step and phase.
- 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.
- For the "Dragons" ability, you decide whether the creature with flying will fight the target creature you don't control as the ability resolves.
