When does Ravenbloom Student's triggered ability get added to the chain - when you play a spell or when a spell resolves?

Ruling: Ravenbloom Student's triggered ability enters the chain after a spell you play resolves, not when you initially play it.

Sequence:

• You play and resolve a spell
• Ravenbloom Student's trigger enters the chain
• Either player can respond to the trigger

Nuances:

• "Playing a spell" refers to the complete action of playing and resolving a spell, which is why effects that care about spells being "played" can see the spell after it resolves
• You can respond to Ravenbloom Student's trigger with spells like Gust to bounce it before the trigger resolves
