It is important to note that when a card is Banished, it is not sent to the graveyard, and so the Deathwish keyword is not triggered. Additionally, there are cards that can activate Deathwish abilities without destroying the unit on which the keyword appears, such as Maerolorn and Ritual Sacrifice.
Deathwish is a card mechanic most commonly associated with the Monsters faction, but it is not unique to them, also appearing as a keyword on Crow's Eye and Sabrina Glevissig.
