Hushbringer

Hushbringer affects a creature's own triggered abilities as well as other triggered abilities that trigger when that creature enters the battlefield or dies. Such triggered abilities start with "when" or "whenever."

An ability that triggers when a card is put into a graveyard "from anywhere" may still trigger even if a creature dies. It will trigger if the ability is of a dying creature that triggers only when that creature is put into a graveyard from anywhere, if Hushbringer is the card being put into a graveyard, or if Hushbringer leaves the battlefield at the same time as the dying creature.

A creature entering the battlefield or dying at the same time as Hushbringer (including Hushbringer itself entering or dying) won't cause abilities to trigger.

Look at each permanent as it exists on the battlefield, taking into account continuous effects that apply to it after entering or before dying, to determine whether any triggered abilities will be stopped from triggering. For example, if a land that has become a creature dies, an ability that triggers when it dies doesn't trigger.

An ability that triggers on an event that causes a creature to die will still trigger. For example, an ability that triggers "whenever you sacrifice a creature" still triggers.

An ability that triggers when a creature "leaves the battlefield" won't trigger if that creature leaves the battlefield by dying.
