When a unit with both a buff token and a -1 debuff from Orb of Regret is saved by Zhonyas (death replaced), do both effects persist on the unit?

Ruling: Yes, both effects stay on the unit when it returns to base from Zhonyas.

Nuances:

• The Orb of Regret debuff only lasts until end of turn as usual (it doesn't become permanent just because the unit was saved by Zhonyas)
