Journey to Eternity and Liliana's Anoint

Brakkis

If you kill a creature with Liliana's Anoint while Journey to Eternity is on the field, the creature will be brought back with Journey to Eternity then be overwritten by the Zombie version that is brought back with Anoint.

They don't stack together; the one brought back with Journey is simply removed. Not exiled, not destroyed. It just goes away.
