When playing Zenith Blade to stun an enemy and move a unit into combat, can you use standard movement to move other units before the showdown initiates, or must standard movement happen before playing Zenith Blade?

Ruling: You must use standard movement before playing Zenith Blade. You cannot use standard movement during combat initiated with Zenith Blade.

Sequence:

• Move units via standard movement first (Sett from base and Fiora from Battlefield B)
• Once you have priority in the showdown, use Zenith Blade to move the other Sett from Battlefield B to Battlefield A
