Does Ravenbloom Student's ability trigger if the spell you play is countered by Defy or Windwall?

Ruling: No, Ravenbloom Student's ability does not trigger if your spell is countered. A spell is considered played when it resolves, so you only trigger Ravenbloom Student's ability if your spell resolves.

Nuances:

• Countering a spell prevents it from being considered "played" for the purposes of triggered abilities
