The City on the Edge of Forever

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)
I — All artifacts and creatures phase out. Create a 0/1 white Human creature token with "Permanents can't phase in." (Treat phased-out permanents and anything attached to them as though they don't exist.)
II — You draw two cards and each player loses 2 life.
III — Sacrifice a creature token. If you do, you gain 5 life.
