Rule 613.1 · Interaction of Continuous Effects
The values of an object’s characteristics are determined by starting with the actual object. For a card, that means the values of the characteristics printed on that card. For a token or a copy of a spell or card, that means the values of the characteristics defined by the effect that created it. Then all applicable continuous effects are applied in a series of layers in the following order:
Subrules
Layer 1: Rules and effects that modify copiable values are applied.
Layer 2: Control-changing effects are applied.
Layer 4: Type-changing effects are applied. These include effects that change an object’s card type, subtype, and/or supertype.
Layer 5: Color-changing effects are applied.
Layer 6: Ability-adding effects, keyword counters, ability-removing effects, and effects that say an object can’t have an ability are applied.
Layer 7: Power- and/or toughness-changing effects are applied.
