415.1 - An instant or sorcery spell is targeted if the text that will be followed when it resolves uses the phrase "target [something]," where the "something" is a phrase that describes an object or player.
502.7.Ruling.1 - The Protection ability does not grant immunity to effects. Only the specific list in Rule 502.7b is granted. So, untargeted spells and abilities can affect the creature. For example, Wrath of God can affect a creature with Protection from White because Wrath of God is not targeted. And creatures with Protection from Red are still affected by the untargeted static ability of Orcish Oriflamme. [D'Angelo 1999/05/01]
Protection gibt Kreaturen auch die Fähigkeit:
"Cant be target of Spells or Abilities", jeweils halt bei einer Farbe. Also im Klartext. Kreaturen mit Protection from White können nicht das Ziel von weissen Spells or Abilities sein.
