Yone, Blademaster

champion unit

[Weaponmaster] (When you play me, you may [Equip] one of your Equipment to me for [A] less, even if it's already attached.) When I conquer a battlefield that was uncontrolled, deal damage equal to my Might to an enemy unit in a base.

Rulings

• If I hold Reckoner’s Arena with Yone, Blademaster, will I place his triggered ability on the chain when the hold effect of Reckoner’s Arena resolves?
• When and how does Yone trigger? If you conquer a battlefield, is it still open?
