When a damage spell with bonus damage from Ravenborn Tome or Annie, Fiery is played and then Mystic Reversal is used on it, how much damage does it deal?

Ruling: Annie, Fiery does not add bonus damage after Mystic Reversal because it is a passive that only affects "your" spells. For Ravenborn Tome, the bonus damage is likely added when the spell is put on the chain, so it would retain the bonus damage after being Mystic Reversal'd.

Nuances:

• The rules for "when you play a spell" triggers with Mystic Reversal are currently unclear and awaiting official clarification
• The Ravenborn Tome ruling is based on interpretation and has not been officially confirmed
