Does Tibbers' "When you play me" text count as an ability that would be buffed by Annie?

Ruling: Tibbers' "When you play me" text is an ability that goes on the chain when played, so Annie will increase the damage from it. All functional text on cards are abilities.

Nuances:

• Flavor text like "Bear hug!" is not an ability
• The ability doesn't need to have a keyword to count as an ability
