418.5a. The values of an object's characteristics are determined by starting with the actual object, then applying continuous effects in a series of layers in the following order: (1) copy effects (see rule 503, "Copying Objects"); (2) control-changing effects; (3) text-changing effects; (4) type-, subtype-, and supertype-changing effects; (5) all other continuous effects, except those that change power and/or toughness; and (6) power- and/or toughness-changing effects. Inside each layer from 1 through 5, apply effects from characteristic-setting abilities first, then all other effects. Inside layer 6, apply effects in a series of sublayers in the following order: (6a) effects from characteristic-setting abilities; (6b) all other effects not specifically applied in 6c, 6d, or 6e; (6c) changes from counters; (6d) effects from static abilities that modify power and/or toughness but don't set power and/or toughness to a specific number or value; and (6e) effects that switch a creature's power and toughness. See also the rules for timestamp order and dependency (rules 418.5b-418.5g). Example: Crusade is an enchantment that reads "White creatures get +1/+1." Crusade and a 2/2 black creature are in play. If an effect then turns the creature white, it gets +1/+1 from Crusade, becoming 3/3. If the creature's color is later changed to red, Crusade's effect stops applying to it, and it will return to being a 2/2. Example: Gray Ogre, a 2/2 creature, is in play. An effect puts a +1/+1 counter on it, making it 3/3. An effect that says "Target creature gets +4/+4 until end of turn" is applied to it, making it 7/7. An enchantment that says "Creatures you control get +0/+2" enters play, making it a 7/9. An effect that says "Target creature becomes 0/1 until end of turn" is applied to it, making it a 1/4 (0/1, plus +1/+1 from the counter, plus +0/+2 from the enchantment). Example: Svogthos, the Restless Tomb, is in play. An effect that says "Until end of turn, target land becomes a 3/3 creature that's still a land" is applied to it. An effect that says "Target creature gets +1/+1 until end of turn" is applied to it, making it a 4/4 land creature. Then you activate Svogthos's ability ("Until end of turn, Svogthos, the Restless Tomb becomes a black and green Plant Zombie creature with 'This creature's power and toughness are each equal to the number of creature cards in your graveyard.' It's still a land.") while you have ten creature cards in your graveyard. It becomes a 10/10 land creature. If a creature card enters or leaves your graveyard, Svogthos's power and toughness will be modified accordingly. If the first effect is applied to it again, it will become a 3/3 land creature again.	418.5a. The values of an object's characteristics are determined by starting with the actual object, then applying continuous effects in a series of layers in the following order: (1) copy effects (see rule 503, "Copying Objects"); (2) control-changing effects; (3) text-changing effects; (4) type-, subtype-, and supertype-changing effects; (5) all other continuous effects, except those that change power and/or toughness; and (6) power- and/or toughness-changing effects. Inside each layer from 1 through 5, apply effects from characteristic-setting abilities first, then all other effects in timestamp order. Inside layer 6, apply effects in a series of sublayers in the following order: (6a) effects from characteristic-setting abilities; (6b) all other effects not specifically applied in 6c, 6d, or 6e; (6c) changes from counters; (6d) effects from static abilities that modify power and/or toughness but don't set power and/or toughness to a specific number or value; and (6e) effects that switch a creature's power and toughness. Within each sublayer, apply effects in timestamp order. Note that dependency may alter the order in which effects are applied within a layer or sublayer. See also the rules for timestamp order and dependency (rules 418.5b-418.5g). Example: Crusade is an enchantment that reads "White creatures get +1/+1." Crusade and a 2/2 black creature are in play. If an effect then turns the creature white (layer 5), it gets +1/+1 from Crusade (layer 6d), becoming 3/3. If the creature's color is later changed to red (layer 5), Crusade's effect stops applying to it, and it will return to being a 2/2. Example: Gray Ogre, a 2/2 creature, is in play. An effect puts a +1/+1 counter on it (layer 6c), making it 3/3. An effect that says "Target creature gets +4/+4 until end of turn" is applied to it (layer 6b), making it 7/7. An enchantment that says "Creatures you control get +0/+2" enters play (layer 6d), making it a 7/9. An effect that says "Target creature becomes 0/1 until end of turn" is applied to it (layer 6b), making it a 1/4 (0/1, plus +1/+1 from the counter, plus +0/+2 from the enchantment).

The values of an object's characteristics are determined by starting with the actual object, then applying continuous effects in a series of layers in the following order: (1) copy effects (see rule 503, "Copying Objects"); (2) control-changing effects; (3) text-changing effects; (4) type-, subtype-, and supertype-changing effects; (5) all other continuous effects, except those that change power and/or toughness; and (6) power- and/or toughness-changing effects.
