[quote=The Deserter]Phase Shift Over-shift: This is one of the weaknesses of Phase Shift Monsters. When a Phase Shift Monster uses all of its Phase Overlays it can use Over shift. Before I explain over shift, I will explain that when a Phase Shift monster has used all of it's overlays it can't use any of it's effects and it's atk and def will remain at the last phase it was in before it used up its Phase Overlays. Over shift will allow you to choose which phase you want your Phase Shift Monster to change into. When you do this you are able to use that phase effect during that turn. If you do this, the monster is removed from play, at the end of the turn the effect was used. When a phase shift monster is destroyed by battle or card effect (other than cards that remove a monster from play) it is sent to the graveyard like other monsters.

Overshift is OPTIONAL! You only banish it if you CHOSE to use Overshift! At the end phase of the turn it uses the last effect it loses the effect. Then at any time you can use one of the effects but banish it at the end phase of that turn.
