In order to both create simpler interactions between evergreens, and to make it easier for the old and the new players to understand the new version of Vigilance, its behavior was simplified to preserve its flexibility when combined with other evergreens. The main interactions are listed below:

  • If a creature with Vigilance has either First Strike or Double Strike, it will check if it's able to deliver a fatal blow on the opposing creature first, and then block or not according to that creature’s power. However, the vigilant creature will not consider if the opposing creature has any of these evergreens (First Strike or Double Strike).
  • In the case of Protection from Color, a creature with Vigilance will check if its toughness is equal or greater than half of the opposing creature's power, rounded up. And, if so, it will block. Otherwise, it will not block. An opposing creature with Protection from Color or Prevent Damage will not affect the Vigilance behavior, as the vigilant creature will only care about the opponent's power, and not its ability to mitigate damage.
  • If the creature with Vigilance also has Prevent Damage, it will always block, regardless of the opposing creature’s power.
