Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Special Summon 1 of your banished LIGHT or DARK monsters. If a face-up Xyz Monster(s) you control is banished, while this card is in your GY (except during the Damage Step): You can banish this card, then target 1 of those monsters; Special Summon it. You can only use each effect of "Galaxy Journey" once per turn.
