- 7 August 2020If there are no other creatures on the battlefield when the morbid ability triggers, the ability must target Morkrut Banshee itself.
- 7 August 2020Morkrut Banshee's morbid ability triggers only once, not once for each creature that has died this turn. If no creatures have died by the time it enters the battlefield, its ability won't trigger at all.
