I have an artifact enchanted with Zoetic Glyph and my opponent casts Ultima. Ultima destroys my creatures and attempts to end the turn. At 722.1c we check state-based actions, at which point my Zoetic Glyph is put into the graveyard due to not being attached to an artifact. This trigger is put onto the stack during the cleanup step (722.1f) and players get priority to act. However, the phase indicator at this point is still showing main phase going into declare attackers
