Does Annie's ability to give +1 damage apply to spells and abilities that don't already deal damage (i.e., that deal 0 damage)?

Ruling: Annie's ability only increases damage for spells and abilities that already deal damage. However, if a card explicitly states "deal 0 damage," then it would deal 1 damage with Annie's bonus.

Nuances:

• The ability specifies "bonus" damage and states "each instance of damage they deal is increased by 1," indicating the card must already deal damage to benefit
• The hypothetical edge case of a card that explicitly says "deal 0 damage" would be increased to 1 damage, though such cards may not exist in practice
