3 rulings from Wizards of the Coast
- 26 July 2024Some creatures have base power and toughness 0/0 and an ability that gives them a bonus based on some criteria. Those are not characteristic-defining abilities, and that ability doesn't change its base power.
- 26 July 2024Normally, a creature's base power is the power printed on the card or, for a token, the power set by the effect that created it. If an effect modifies a creature's power without setting it, that is not included when determining its base power.
- 26 July 2024If a creature has a characteristic-defining ability that sets its power, indicated with a */* or similar in the power and toughness box, that ability is taken into account when determining its base power.
