If my opponent attacks a battlefield where I have a unit and plays Rebuke (which resolves), can I then play Zenith Blade to move another unit from base into the showdown?
Ruling: Yes, you can play Zenith Blade after Rebuke resolves. You will stun one of their attackers, then move a unit into the showdown where it becomes a defender.
Sequence:
- Rebuke resolves
- You play Zenith Blade on your action
- Stun one of their attackers
- Move a unit into the showdown
- The unit becomes a defender
Nuances:
- Showdowns and combat do not end until both players fully pass focus
- You cannot lose control of a battlefield while a combat is happening
