Hushbringer

Replacement effects are unaffected by Hushbringer's ability. For example, a creature that enters the battlefield with one +1/+1 counter on it will still receive a +1/+1 counter, and Leyline of the Void will still exile creatures that would die.

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."

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.
