Lifelink

If it's neither day nor night, it becomes day as Celestus Sanctifier enters the battlefield.

Whenever day becomes night or night becomes day, look at the top two cards of your library. Put one of them into your graveyard.

Kicker (You may pay an additional as you cast this spell.)

When Kor Sanctifiers enters the battlefield, if it was kicked, destroy target artifact or enchantment.

Protection from black and from red

When Sanctifier en-Vec enters the battlefield, exile all cards that are black or red from all graveyards.

If a black or red permanent, spell, or card not on the battlefield would be put into a graveyard, exile it instead.
