Tomb of Annihilation creates The Atropal, a legendary 4/4 black God Horror creature token with deathtouch
The trigger event doesn't have to specifically refer to "creatures." In these cases, the trigger event may also refer to something being "put into a graveyard from the battlefield." For example, if the equipped creature or an emblem you own has an ability that triggers "whenever an artifact is put into a graveyard from the battlefield," that ability would trigger twice if an artifact creature died
While the counter on its own is a one time thing, having this trigger at the beginning of combat and then the ability to get that creature back with haste for that same combat makes a very tight window for opponents to deal with your shenanigans
