418.5b. If an effect should be applied in different layers, the parts of the effect each apply in their appropriate layers. If an effect starts to apply in one layer, it will continue to be applied to the same set of objects in each other applicable layer, even if the ability generating the effect is removed during this process. Example: An effect that reads "Wild Mongrel gets +1/+1 and becomes the color of your choice until end of turn" is both a power- and toughness-changing effect and an "other" kind of effect. The "becomes the color of your choice" part is applied in layer 5, and then the "gets +1/+1" part is applied in layer 6. Example: Grab the Reins has an effect that reads "Until end of turn, you gain control of target creature and it gains haste." This is both a control-changing effect and an "other" effect. The "you gain control" part is applied in layer 2, and then the "it gains haste" part is applied in layer 5. Example: An effect that reads "All noncreature artifacts become 2/2 artifact creatures until end of turn" is both a type-changing effect and a power- and toughness-setting effect. The type-changing effect is applied to all noncreature artifacts in layer 4 and the power- and toughness-setting effect is applied to those same permanents in layer 6, even though those permanents aren't noncreature artifacts by then.	418.5b.

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 (layers 4 and 6b). An effect that says "Target creature gets +1/+1 until end of turn" is applied to it (layer 6b), 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 (layers 4, 5, and 6b). 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.
