If you use Zenith Blade to move into a showdown, and that movement causes a unit you control to enter another battlefield with enemy units, does that create a second showdown that resolves after the first?

Ruling: Yes, moving a unit you control into another battlefield with enemy units creates a second showdown.

Sequence:

• The first showdown begins
• The second showdown waits for the first one to finish
• After the first showdown resolves, the second showdown resolves
