Can you play an Action spell (Rebuke) in response to an opponent's Time Warp?

Ruling: No, you cannot play Action spells in response to Time Warp. Actions can only be played on your turn when nothing is happening, or during any showdown when the chain is empty and you have focus.

Nuances:

• Only Reaction spells can be played in response to opponent's spells like Time Warp
• Action spells have specific timing restrictions that prevent reactive play
