Can you make an opponent miss the timing of Defy or Windwall by chaining another card in response?

Ruling: No, you cannot make an opponent miss timing through chain blocking. The opponent can use Defy on any spell on the chain that matches Defy's restrictions (no more than 4 energy and no more than 1 power).

Nuances:

• Chain blocking does not exist in Riftbound
• Counter spells like Defy can target any valid spell on the chain, not just the most recent one
