Normally, a creature’s base power and toughness are the power and toughness printed on the card or, for a token, the power and toughness set by the effect that created it. If another effect sets a creature’s power and toughness to specific numbers or values, those become its base power and toughness. If an effect modifies a creature’s power and/or toughness without setting them, that is not included when determining its base power and toughness.
