Enchant creature
Enchanted creature gets +1/+2 and has vigilance.
Addendum — When this Aura enters, if you cast it during your main phase, enchanted creature gains lifelink until end of turn.
(25/01/2019)
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.

If an effect copies a spell with an addendum ability while it's on the stack, the copy wasn't cast at all, so you won't get the addendum bonus.

If Sentinel's Mark enters the battlefield without being cast, the addendum ability won't trigger, even if it's your main phase.

Multiple instances of lifelink on the same creature are redundant.
