This explplanation here helped me make sense of Phase Shift monsters, though the part where effects are negated after the overlays are gone makes me think: if you are meant to detach the second willingly, then what is the point of doing so if the effects just get negated? The whole Overshifting part didn't make sense after that, so I opt to ignore the effect negation and merely stick with Phase Shift monsters just getting banished at the end phase. Does that sound good to you guys?

I'd rather have the effect last until the end of the turn, then you can use Overshift one last time.
