- 23 June 2020The triggered ability triggers just once, no matter how many creatures died this turn.
- 23 June 2020If a creature didn't die before your end step begins, Sabertooth Mauler's ability doesn't trigger at all. The creature may have died before Sabertooth Mauler entered the battlefield, however.
