Does Ravenbloom get +1 when you reveal a hidden spell?

Ruling: Ravenbloom does not get +1 when you reveal a hidden spell. It gets +1 when you play the spell, which occurs after the spell resolves when you flip it up on a later turn.

Sequence:

• Hiding a spell is not considered playing it
• When you flip the hidden spell up on a later turn, you are playing it
• The playing occurs after the spell resolves
• Ravenbloom gets +1 at that point

Nuances:

• The act of hiding a spell does not trigger Ravenbloom
• Only the actual playing (after flipping and resolving) triggers the +1
