① The effects of face-up monsters on the field are negated.
● Monsters can still activate their effects.
● This only negates the effects of monsters while they remain face-up on the field.
If a monster activates its effect on the field, but isn't face-up on the field when that effect resolves (EG, Lonefire Blossom tributing itself), that effect is not negated.
