FlashEnchant creatureEnchanted creature gets +1/+2 and has vigilance.Addendum — When Sentinel's Mark enters the battlefield, if you cast it during your main phase, enchanted creature gains lifelink until end of turn.
Rulings:
- 1/25/2019 If Sentinel’s Mark enters the battlefield without being cast, the addendum ability won’t trigger, even if it’s your main phase.
- 1/25/2019 Gaining vigilance any time after the moment you choose to attack with a creature won’t cause it to become untapped, and losing vigilance after that time won’t cause it to become tapped.
- 1/25/2019 Multiple instances of lifelink on the same creature are redundant.
